What is int of e^(arctan(y)) / 1+y^2 dy, from -1/sqrt[3] to

[Messagehelp]

What is the integral of e^(arctan(y)) / 1+y^2 dy

if the numbers are top: 1/squareroot3, bottom: -1/squareroot3

I have no idea how to do this. show me?

substitute

\(\displaystyle u \, = \, \tan^{-1}y\)

Re: Whats the integral?

What is the derivative of \(\displaystyle e^{\arctan (y)}\)?
