Use arctan(x) and partial fractions, then x = atan(theta) for 1/1+x²

Alyx :
way too complicated, you can either to x = tg t and one of the 1+x^2 will turn into 1/cos^2 t which is dt, or you could also split the fraction into (Ax +B)/(1+x^2) + ( Cx + D)/(1+x^2)^2

Come off it. This technique was known at least 200 years earlier.
