Integral from 0 to 1 of arctanx/(1+x)

[@holyshit922]

Integration by parts with
u = arctan(x) , dv = 1/(x+1)dx
Substitution u = (1-x)/(1+x)

I think you can make these videos shorter and better if you combine some of the obvious steps. But good video otherwise.

Or just do x=(1-t)/(1+t) just like cipher did and solve it in 3 minutes

Sure, but there's always multiple ways to approach things and not just one.
