Question

defined function g(x) = \[\ln ( x ^{2} + 1)\]
primitive calculates g whose graph passes through the origin of coordinates

Answer 1

I'm sorry, what was the question? :3

Answer 2

\[\int\limits\ln ( x ^{2} + 1)\]

Answer 3

ok start with integrating by parts

u = ln(x^2 +1) dv = dx
du = 2x/(x^2 +1) v = x
