Did you cover double integrals?

Yes, as a matter of fact.

Hey I am new to this site but I was wondering what software you are using to display the integrals.

I looked at the problem and was going to propose a direction to try. If you do integration by parts you get u=arctan(x) dv= 1/ln(1+t)

I was thinking that 1/ln(1+t) might be a workable integral. What calculus level are you taking?

The "LaTex" software is built into the site. Look at the thread http://www.mathhelpforum.com/math-help/f47/
