Learn how to solve integral calculus problems step by step online. Find the integral int(x^(-2)-sec(x)^2x+3)dx. Expand the integral \int\left(x^{-2}-x\sec\left(x\right)^2+3\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. We can solve the integral \int-x\sec\left(x\right)^2dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du. Now, identify dv and calculate v.
