Learn how to solve problems step by step online. Integrate int(x^3cos((x+1)/2)(4-x^2)^(1/2))dx. We can solve the integral \int x^3\sqrt{4-x^2}\cos\left(\frac{x+1}{2}\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.
