$5\int x\sin\left(-4x\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int(5xsin(-4x))dx. The integral of a function times a constant (5) is equal to the constant times the integral of the function. Use the odd-even identity \sin(-\theta)=-\sin(\theta). We can solve the integral \int-x\sin\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 u and calculate du.
