Hi everyone,

Can someone give me a hint on this one, please?

I have the integral from 1 to the square root of 3 arctan(1/x) dx

I said that u=arctan(1/x)

du=????

dv=???????

v=???????

I'm not sure if my u is correct or not. I don't think it is because now I can't choose anything for du, right? Should it be u=arctan and du=1/x????

Thank you
