Learn how to solve integrals of exponential functions problems step by step online. Find the integral int(e^xcos(x))dx. We can solve the integral \int e^x\cos\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 u and calculate du. Now, identify dv and calculate v. Solve the integral.
