Hey guys, I have this problem I have been trying to solve for the longest time.
Not looking for a complete solution, maybe part of one would be nice.
I'm trying to integrate
So far I have tried 2 ways of going at it.
First I completely expanded the integral
I have no problem integrating
I just simply use the substitution technique.
The next part gets tricky, I'm stumped. Any of the functions with x variables I simply can't seem to do.
I tried substituting by parts by either making or so on and so forth
I went to wolframalpha.com and tried to understand what they did step by step
For example, I tried to integrate just like the site did. They say to substitute and to get
Either I am feeling really dumb right now and the answer is right in from of me or the answer is completely wrong. How did wolframalpha manage to get
All help is greatly appreciated
I'll do a step-by-step solution if you're having difficulty with the integral. Or just to give you something to compare your work to.
Then, let , hence ie. .
So by multiplying out we get , since we get
, which we can actually further factor to give where of course.
