$\sin\left(4\right)\int x^3\cos\left(4x\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int(cos(4x)sin(4)x^3)dx. The integral of a function times a constant (\sin\left(4\right)) is equal to the constant times the integral of the function. We can solve the integral \int x^3\cos\left(4x\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.
