Unlock this full step-by-step solution!

Learn how to solve problems step by step online. Solve the trigonometric integral int(sin(4x)cos(2x))dx. Rewrite the trigonometric expression \sin\left(4x\right)\cos\left(2x\right) inside the integral. The integral \frac{1}{2}\int\sin\left(6x\right)dx results in: -\frac{1}{12}\cos\left(6x\right). The integral \frac{1}{2}\int\sin\left(2x\right)dx results in: -\frac{1}{4}\cos\left(2x\right). Gather the results of all integrals.

Final Answer

$-\frac{1}{12}\cos\left(6x\right)-\frac{1}{4}\cos\left(2x\right)+C_0$
