Final answer to the problem
Step-by-step Solution
Learn how to solve integrals of exponential functions problems step by step online. Find the integral int(2020cos(2020x)e^x)dx. The integral of a function times a constant (2020) is equal to the constant times the integral of the function. We can solve the integral \int e^x\cos\left(2020x\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.
