Okay, I have a question. Is equal to ?
I am working on this problem,
, it's actually tan^-1(2x) but I'm not sure how to insert the negative to make it the inverse.
I made
Am I heading in the right direction? Thanks in advance.

Hello,
No, we have or .
Write [tex]\tan^{-1}[/tex] or [tex]\arctan[/tex] .I am working on this problem,
, it's actually tan^-1(2x) but I'm not sure how to insert the negative to make it the inverse.
I don't think so since you don't know an antiderivative of . One possibility is to see that if you let and then and so is a rational fraction : we don't have to integrate anymore.I made
Am I heading in the right direction?
Does it help ?
The terms in red should be 2, not 4.
Now, from here, do the following:
We found that
The integral reappears on the right side! So get it on the left side!
Before we get our answer, try to evaluate the integral I highlighted in red.
Hint : apply integration by parts! Let .....
Yea, I see what you mean!
How does it become 3/2 on the left side? I know its because you put the integral to the left though like you said, but how exactly?
Okay, I never thought of it like that, I'm going to try that now.
