Homework Statement
f'(x)= (2+x^2)/(1+x^2) Find anti derivative
Homework Equations
The Attempt at a Solution
I attempted to bring the denominator up using (1+x^2)^-1 and i also tried long division to simplify but had no luck...
1/(1+x^2) is the inverse tan derivative, but what can i do from here:
(2+x^2) * 1/(1+x^2) is substitution legal here?
