IQ test
Let's see what you got /b/
>>705254533
I'm not doing your fucking homework for you, faggot.
11
>>705254533
Do your own god damn homework, you faggot.
>>705254533
42.
Also: make your own homework you filthy sixth grader.
>>705254784
This is correct.
>>705254533
IQ tests dont have math problems you stupid nigger
11 or gtfo
>>705254533
You can't solve it, f(t) could be anything
>>705255004
f(t) can only be 11, you pleb. You're given a definite integral with a known value. Go study moar fine arts
>>705255212
the answer is not 11.
just checked
impossible to answer. next question.
>>705255212
Youre shit at maths. kys fam
>>705255212
f(t) could be: 20t + 1
You filthy casul
>>705255212
A.. are you serious?
Because right now I can name two functions off the top of my head that will equal 11 when integrated from zero to one.
f(t) = 22t
f(t) = 18t^2 + 12t
>>705255212
you know nothing about f(t). cannot answer.
>>705255397
>>705255400
If a function equals 11 from 0 to 1, then 4 times that function from 0 to 0.25 equals 11.
Nignogs.
>>705254533
F(1)-F(0)=F(4*0,25)-F(4*0)=11
Duh.
Absolutely 11. At least this one is actually basic calculus instead of ez pz order of operations
>>705254533
nice dubs https://www.youtube.com/watch?v=HDKLvRHkGLo
>>705255793
This is correct
>>705255754
I'm sorry but you are retarded
>>705254533
I can't solve a fucking algebra problem with symbols that I don't understand, nigga
seriously what the fuck is that at the start of the equation??
also there's no critical thinking in this problem, it's just spouting out math knowledge, therefore not an accurate test of IQ
11
iq tests r based on patterns and memorization
OP here, the answer is NOT 11
>>705255679
f(t) = 18t^2 + 12t integrated from 0-1 is certainly not 11, fam. Maybe you meant 10t for 2nd term.....
Kys.
>>705255679
A.. are you serious?
If you integrate 22t wrt t then you get 22t^2
You complete asshole.
>>705255793
Concise and correct. Well done no-bullshit anon.
Since you don't know what f is, even if you can't remember how integration works you can deduce the answer. Anything that requires integrating over a different range is unknowable. If there is an answer, it must be the exact same as the first example, otherwise it could be anything.
>>705254533
We have never done this in my school, I don't know what this means, but I have had my IQ tested before and I got a general IQ of 121. I have a good verbal IQ, but my problem solving skills is where I really shine.
>>705256623
Tfw you forget to divide by new exponent
>>705254533
I don't understand this shitty puzzle. What is the function OP?
1
understanding calculus has nothing to do with IQ. How you made it to calculus will always be a mystery to me.
69 LOL
Bo ho y u do this op my precious iq
>>705257033
i have some idiot mother fuckers in my circuits class which prereq is calc 3.
dont be surprised of anything.
im a senior btw i just put off the class because its disgusting electrical engineer shit
knowing calculus isn't an indicator of intelligence, it's an indicator of arbitrary and esoteric knowledge.
by OP's logic, only stem people are intelligent, so every author, artist, musician, composer and pretty much every non-science field wasn't smart.
you can replace that calculus problem with any arbitrary thing like what's the melting point of steel beams, knowing that or not knowing that won't make you any more or less intelligent.
>yfw everybody is either a troll or stupid.
>I think mostly trolls though.
>>705256525
Should be 15t^2. Mistype
>>705256623
1/2*22t^2 [t=0,1] = 1/2*22-0 = 11
>>705254533
no solution.
11/4
>>705257275
>knowing calculus isn't an indicator of intelligence, it's an indicator of arbitrary and esoteric knowledge.
I can smell your piss bottles from here, neckbeard.
>>705257424
niggah
>>705257275
t. psych major
also 1538 degrees c 1153 c if we're talking liquidus region and not mush zone. most likely ~1520 c for A36.
>>705254533
t = 4u, t/4 = u, dt = 4du
integral from 0 to 1 of f(t)dt = integral 0/4 to 1/4 of f(4u)*4du = 4*integral from 0 to 0.25 of f(4u)du = 11. So, integral from 0 to 0.25 of f(4t)dt is 11/4.
>>705257424

>>705254533
IQ tests don't require a semester of calc
>>705257846
GENIUS
THIS GUY WINS, THE REST OF YOU ARE RETARDS
>>705257432
I'm not a neckbeard, I'm a musician, a classical one with quite a lot of education. I don't know calculus but I can identify every baroque dance by its time signature and style, figure out the structure and chord progressions of pieces by ear and can play very advanced things on the piano.
I could've started a thread asking you about any of the facts of my trade and said "IQ test," but that doesn't make much sense, does it? That's because I know very specific things pertaining to my degree of study, and so do you. Me not knowing calculus doesn't make me any less intelligent. Likewise, you not knowing the difference between second and third species counterpoint doesn't make you any less intelligent.
>>705254533
thats not iq but knowlege you fucking idiot
>>705257846
no
the function could literally be any function. we can't know just from input, especially since it's a fucking definite integral.
>>705258263
triggered fatass
>>705257432
Are you retarded? I have an economics and management class in Oxford University and the few well adjusted human beings who aren't either autistic, beta orbiter cucks or SJW, feminist cunts are doing economics, physics or one of the several history subjects.
>>705258539
I'm not triggered, I enjoyed writing that.
I'm 6'3 175lb for that matter.
>>705255400
just make up a random f(t) and see for yourself
>>705258589
>>705254533
Compared to an original function y=f(x), a second function y=f(4x) represents a dilation in the x-direction.
Each point (x,y) on the original graph is now at (x/4,y). So the value x=1 on the original graph corresponds to the x=1/4 on the second graph (Ie: the limits on the integrals represent corresponding points on the function)
Essentially the graph is compressed into a quarter of its original width. The area under the graph would also be compressed - to a quarter of its original size.
Therefore if given:
∫ f(t) dt = 11, for 0<t<1
It follows that:
∫ f(4t) dt = 11/4, for 0<t<1/4
>>705255631
this
there is not enough information given. You could make any number of valid f(t)s that satisfy the first equation that yield different answers on the second.
>>705258682
just like you enjoy taking cock and wasting time by studying worthless shit
>>705258821
ANOTHER WINNER
>>705258821
Well done, anon. A true demonstration of how integrals actually operate instead of attempting to regurgitate memorized steps. My soul can go in peace now
<3
f(t) = 11t
f(4t) = 44t
44(0.25) - 44(0) = 11
I think the answer is 11
Here is the answer
>>705256629 This is me
Hold the fuck up, I'm an idiot.
These guys are right
>>705257424
>>705257846
>>705258821
Fuck, I'm doing a degree where I do calculus every day and I fucked this up. What have you done to my thinkmeat, /b/?
>>705259810
COULD SOMEONE REGURGITATE A FORMULA OR TO FOR ME TO UNDERSTAND
>>705258488
Yes you can, because we know that integral 0 to 1 of f(t)dt = 11, we know that f is integrable on [0,1]. If we use the u substitution t = 4u on the interval [0,0.25], then the graph of f(4u) is just the graph of f(t), except squeezed tighter. Applying the riemann sum definition of integration, we see that if we choose the partitions of [0,0.25] to be scaled down versions of the partitions of [0,1], then each of the columns in the area approximations of f(4u) will have exactly the same height as the columns in the area approximations for f(t), but the width of each column in the area approximation for f(4u) will be exactly 1/4 of the width of the corresponding column in the area approximation for f(t). So, the area of each column will shrink to a fourth of its original size, proving that the area under the curve for f(4u) on [0,0.25] is one fourth of the area under the curve for f(t) on [0,1].
>>705259694
you fucked up the u subsitution
>>705259960
Well if you don't know any calculus yet, it's not just one formula. Also explains why this is a shit IQ test, it just tests if you've been taught integration, differentiation, and that thing where you swap out the du that I can't remember the name of right now.
>>705259694
You didn't actually integrate though. End of the first line, you go straight from the integral of f() to f(). That's wrong.
the simplest way for you dense motherfuckers to understand that the answer is 11/4 is to integrate the simplest f(x)=11 there is, which is
f(x)=11
so basically just draw a horizontal line. The integral is equal to the area beneath the function. Therefore, if you integrate from 0 to 1 you get a rectangle with dimensions 11 x 1,
Then integrate the same function from 0 to 0.25 and you will get another rectangle but with different size (11 x 0.25)
>>705260028
you're right i just spent a while toying with wolfram
>>705260677
An integral wouldn't be a constant, anon. It's 11.
>>705254533
f(t) = 11t
t=4u
u=t/4
du=-4/t^2 dt
Integral f(4u)du = Intergral f(t)(-4/t^2)dt
Integrate with limits
Answer is infinity
>>705254533
Iq test are soposed to factor age and education, you don't just toss out a problem. Also
>>705261099
wrong faggot
Answer is 9
>>705261099
you fucked up the differentiation step, d(t/4) = (1/4)dt, not (-4/(t^2))dt.
>>705257424
Really sad I had to scroll this far to find the right answer.
The answer is 11/4
Let y = 4t
Then f(4t) = f(y), and dt = 1/4 dy
So you are integrating 1/4 f(y) dy from y=0 to y=1, which is just 1/4 of the original integral.
>>705260351
not needed, he is right
>>705261527
But no
That's wrong
>>705261527
you cant change f(t) to f(4t) without a u substitution
>>705261093
sorry... the integral would be 11 t
the function would be f(x) = 11
and the integral would be = 11 t evaluated from 0 to 1
>>705261344
oh yeah good point
answer is 11/4
>>705261826

*stupid variable change: u=4t
* this variable change is acceptable because it is a C1 variable change = u(t) = 4t is derivable and its derivative is continuous on [0,1]
* (noone bothered mentioning that essential argument fecking retards here)
* thus: du=4dt
* so dt = 1/4 du
* 0≤t≤0.25 thus 0≤u=4t≤1
* second integral is int_0^1 f(u).dt/4
* this is 1/4 * int_0^1 f(u)du by linearity of the integral operator
* (noone mentioned that essential argument fecking retards here)
* feckin second integral = 1/4 of the first
all of you are niggas not even caring justifying their calculations
bastards
>>705254533
That isn't an IQ type problem, that is calculus. IQ problems are designed to test the capacity of your ability to solve problems, not to see if you have made it to calc1 in school yet.
Now finish your match homework and go to sleep. You need proper rest or you won't make it through the eighth grade.

Things are assumed. When we're going up against "there is no answer hurr durr", do we really need to explicitly say u=4t is integrable.

whereas this is just a feckin sketch
and he will go back home happy
when he did not even learn the proper reasons why his calculation was right
one day he will do stuf like u = abs(t-1) and he will struggle, not even knowing what's happening
>>705255400
The answer is 11/4 or 2.75. Consider the case where f(t) is 11. So you have integral from 0 to 1 of 11dt. That would integrate to 11x from 0 to 1 which is just 11. Now with that 4 there, it wouldn't do anything at all to that equation. You would still have the integral from 0 to 0.25 of 11dt but this time your answer is 11t from 0 to 0.25 which is 0.25 * 11.
>>705267573
>"loose face"

>>705254533
let u = 4t
when t = 1, u =0.25
when t=0, u=0
therefore, integrating f(u) from 0 to 0.25 is the same as integrating f(t) from 0 to 1, meaning f(4t) = 11
>>705268854
>I think
but you dont have a brain how could you possibly
>>705268840
Pick out which posts are mine and you get a non-prize.
>>705268942
you forgot the du = 4dt step
>>705261739
Second integral is f(4t)
So you get 4(11 x 0.25)
So you get 11.
How do you do these a again?
Find the integral with respect to the lower bound and upper bound?
>>705255679
He's trying though, that's the most impressive part. Keep it up, you'll get there!
>>705269267
11 = f(t)
11 = f(4t)
>>705269077
this one
>>705269305
yeah you solve the integral then plug in the higher minus the lower solution.
only this is theoretical
As an engineering student with over 2 years of experience in calculus you don't know how I'm having the biggest chuckles in my life with all these autistic Googles kekz
>>705255754
Function is four times bigger.
Range is four times smaller.
Answer = the same.
It's 11.
>>705269464
You still need to sub out the dt. It's not some magic incantation, it has meaning. dt = du/4
>>705269464

Because guaranteed replies.
>>705267890
let u = 4t. du = 1/4dt. t value of 0.25 = 1 for u
So you have integral 0 to 1 of 1/4f(u)du = 1/4 * integral 0 to 1 of f(u)du
if integral 0 to 1 of f(t)dt was equal to 11 for ANY t, then integral 0 to 1 of f(u)du is also 11. So your answer is 1/4 * 11 = 11/4
>>705269464
you're a inert faggot
coz 400% more and then 400% less is
x(1+400%)(1 - 400%)=x times (1^2 - 4^2)
so answer is -15 x 11 = 165
(rember to add 1 to 5 when multiplying by 11)
Stupid retarded niggers.

You're absolutely retarded not seeing its 11.
This has nothing to do with IQ and more the level of math you've graduated from btw.
>>705269729
This is true but your du = 1/4dt is technically wrong. It should be based off this:
u = 4t
du/dt = 4
du = 4dt
dt = 1/4du
The rest of your answer is good though.

because pianists have an effect on the world
>>705275669
actually I take this back
pianists have a negligible effect on the world. It's when they band together (assuming there's enough of them, e.g. feminists, jews, niggers, etc.) that they actually become a problem and think that they matter

If everyone thought like you, there'd be no movies, no movie soundtracks, no plays, concerts, shows, books etc. The notion that you're doing some self-righteous God's work by doing stem is pretty ridiculous.
>>705275661
If you think it's useless and dead, then that's really your loss not mine. It's very indicative of your lack of culture and overall intelligence.

is it tho
i'll be enjoying my money and family while you're homeless in the streets trying to get mcdonalds to accept your application because you went to devry for music.
>>705276085
>devry
kek. I won't say my school on here, but I'll say that it's in the top 40 of public universities in north america.

If by books you mean novels, etc. then I would be fine with that. I don't read em. I don't watch TV or movies either. I don't listen to music.
Regardless, I didn't say everyone should stop playing music and participating in the arts. I play guitar. I just don't live my life thinking I should only play guitar. Those who do are idiots.

cool dude is the list from huffington post?
be sure to put that on your resume to mcdonalds

I put an ad out on craigslist once and got like 50 replies immediately for piano lessons, you'd really be surprised how in demand even the lowest level of artists are in big cities.
>>705276356
Sure, that's perfectly respectable. If I didn't have a calling for music I'd definitely go into stem, I love CS, learned a bit of Java before, built my own computer, dual boot linux etc. I really like computers.
I have such a burning desire to play music that it's what consumes the majority of my thoughts every day, and has consumed them for a decade. It'd be a crime to my own existence to not pursue my passion.

you're killing me anon.
>>705276718
Care to explain? I was top of my class in high school and could've gone to any college, but this is what I chose to do. I don't get why you chose to belittle me for any other reason than to make yourself feel better.
>>705276948
you're literally in this thread shitposting because you're so insecure about the fact that you're down a path to no where.
im starting to genuinely feel bad for you.
