There ya go.

Let u = 1/(1+x^2)

Remember ILATE

2 years ago I could have helped you. Got any others?

Didn't realize it broke the image, thanks for fixing it

I guess that's supposed to be the correct answer for it somehow, teach is an ass and I can't understand math, they said the answer looks like "(π/a) x lnb", sorry if I'm bugging you or wasting time
Not good with math, not even sure what ILATE is

Nope, sorry

I don't think we can use integration by parts here though

oh boy, a u substitution. Here we go

literally just google a written out version of the problem

bump

Type it into wolframalpha dot com like everyone else

I also need help what’s the best site to acquire virtual numbers to bypass a mobile verification

i was taught liate

Lol I don't think we actually use that. I was just trolling

fucking symbolab dude

This

Use fucking wolfram alpha, it can solve anything

He needs to actually learn how to do these but yeah use a CAS or something to help

I have a solution. Just need a moment to write it out.

symbo shows enough of the steps for free that you can figure out how to do it all if you paid any attention in class.

it actually helped me a lot

Yeah don't get me wrong they are very helpful learning tools if not abused.

you have to use u substitution and the chain rule but it's a very complex solution

yea it gets sketchy when chegg gets involved.

What do we use for u?

Then what can be used?

bump

well our choices in any integral are:
1. Simplify algebraically so that we can apply a formula right out of the box, which doesn't look possible here
2. U sub, which isnt immediately apparent to me what u would be
3. Trig identities
4. Trig sub
5. Integrate by parts
6.partial fractions
Are there any others? It's been a while since I've had to take an integral

>well our choices in any integral are:

We have way more tricks than that up our sleeves tonight, kohai.

Sorry user I'm in school right now, only in pre-calc though. Not done integrals yet :(

Lol are you going to evaluate them as limits or something crazy?
OP are you still around?

Substitute x=tan u and then integrate by parts

I'd do it for you but I'm on the can currently.

I'm going to do some wild stuff.

u sub and use tanx

So this is what STEMlords do for fun...
I think I'll stick to saving the world, please.
>Or should I say: your welcome.

Hold on, I've picked up some fucking term that isn't doing what I want it to.

Yeah still around, just not posting much since I don't understand math
I don't really want to interfere with anything, just ask if you need more info and I'll give anything I can get

Found the issue, I had to restart.

It's just an alteration of your trig identities. Use this to start.

eat shit pal

turn rightside up

You guys ready for this dank-ass shit?

Trig sub OP

Already did that

What was it?

I have integrated it without taking the antiderivative of the integral in question. I just need to take a moment to take a pic of the solution.

I have omitted the details of the partial fraction expansion for brevity and I have assumed you know the antiderivatives of t/(t^2+1) and 1/(t^t+1). This technique is called differentiation under the integral sign and was a favorite of the late Richard Feynman.

And for anyone that can't read my shitty writing the final line is I=πln(2)/8.

>1/(t^t+1)

Meant to write t/(t^2+1).

Nice

Aye OP here, not sure if you guys have this finished or not, but when you do just reply to this with the answer.
Also got a little info that may fuck up stuff or maybe not, someone said this is supposed to be integral calculus, sorry if I just fucked everyone and their progress, I'm a little bit of an idiot

>t/(t^2+1)

1/(t^2+1), gah

I don't think you're cut out for a career in mathematics. Your work is far too legible and organized. I hope this is at least the third draft.

Second draft on paper. I guess I'm no math god.

Oh, the issue was that I had a -1 that appeared because I wrote an x as an α in one of the first steps, this carried to the end of the problem. I figured the integral would be something like I=(p/q)(π^n)ln(k) and I knew I'd eventually get to something like I=2(p/q)(π^n)ln(k)-I. I was able to tell that anything of the form I=2(p/q)(π^n)ln(k)-1-I is wrong because then I couldn't get rid of the -1.
