Ok, I have the following two problems:

[tex] \frac{d}{dx} \ \int_0^1 \ e^{tan^-1(t)} \ dt \\\\

[/tex]

and

[tex]

\int \ \frac{Sin[x]}{1+x^2} \ dx

[/tex]

I have tried to do substitution on both and integration by parts on the second one but nothing seems to work. If I could just get some pointers in the right direction on where to start that would be awesome, thanks a lot.
