Learn how to solve integrals of exponential functions problems step by step online. Find the integral int((x^2)/(1+x^2))dx. Divide x^2 by 1+x^2. Resulting polynomial. Expand the integral \int\left(1+\frac{-1}{1+x^2}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int1dx results in: x.
