Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm a bit confused as to what I should assign u and dv in this integration by parts:

ln(1+x^2)dx

I remember a general rule called the "LIPATE" rule... which is basically Logarithms, inverse trigs, poly, algebra, trig, then exponentials...

Now... would I assign u = ln(1+x^2)? and dv = dx?

That kind of defeats the purpose of integration by parts... doesn't it?

I'm probably not assigning u and dv properly... so if anybody can lend me a hand, thank you!
