Solve this b

Solve this b.

not gonna do your homework faggot.

x = OP is a faggot

x= 3,25

-2 tan^(-1)((4+x)/2)+1/2 log(20+8 x+x^2)

Faggit

1/2 (log(x(x+8)+20)-4 tan^(-1)((x+4)/2)) + C

But that's wrong faggot

You retarded?

from -inf to inf or what?

No boundaries idiot. So just solve the integral and put a constant after it

Obviosuly, shitbird. If it wasn't it would have boundaries.

Undefined.

Wolfram alpha can do ur home work kid

...

see

How do you do this? I forget how to hard math anymore.

that's the exact same thing you retarded faggot kill yourself

underrated

Done.

Look up partial fraction decomp

seems to be legit

But that's not how you solve this (The denominator is irreducible in R)

Although you could solve it that way, using complex numbers.

Better one

...

is that a substitution method? ive never understood how to do that

Write x = some function of u := f(u) e.g. x = u-4
Then replace x with f(u) and "dx" by "dx/du du"

e.g. dx = 1 du in this case because d/du (u-4) = 1

Also if you're integrating between limits you replace the limits with f(limits).

Mathfag here - AMA

why?

Why not?

Integrals? Dude thats fucking easy

Idk dude i wanna but i get actual headaches from math

Let R → S be a local homomorphism of complete local domains. Prove that there exists an R-algebra B_R that is a balanced big Cohen-Macaulay algebra for R, an S-algebra BS that is a balanced big Cohen-Macaulay algebra for S, and a homomorphism B_R → B_S such that the natural square given by these maps commutes.

Describe Fourier Transformations.

This is high school calculus......

Because who cares that you're a mathfag

Nothing wrong with reddit but that's the sort of place to post your lame AMA shit unless you're actually interesting

Sorry, I didn't take pure maths to such a high level.

Discrete: A simple basis transformation onto a basis given by sines

Continuous - Again, a basis transformation but this time in the space of periodic infinitely differentiable functions. We also often extend it to functions outside this space.

Both are basically a decomposition into different frequency sinusoids.

I'm not interesting - That's why I'm posting on Sup Forums
