Learn how to solve integral calculus problems step by step online. Find the integral int(arctan(x)(1+x^2)^(-1))dx. We can solve the integral \int\left(1+x^2\right)^{-1}\arctan\left(x\right)dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify or choose u and calculate it's derivative, du. Now, identify dv and calculate v. Solve the integral to find v.
