Step-by-step Solution

Problem to solve:

$\int\sin\left(4x\right)\cdot\cos\left(2x\right)dx$

Specify the solving method

1

Rewrite the trigonometric expression $\sin\left(4x\right)\cos\left(2x\right)$ inside the integral

$\int\frac{\sin\left(6x\right)+\sin\left(2x\right)}{2}dx$
2

Take the constant $\frac{1}{2}$ out of the integral

$\frac{1}{2}\int\left(\sin\left(6x\right)+\sin\left(2x\right)\right)dx$

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. Take the constant \frac{1}{2} out of the integral. Expand the integral \int\left(\sin\left(6x\right)+\sin\left(2x\right)\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \frac{1}{2}\int\sin\left(6x\right)dx results in: -\frac{1}{12}\cos\left(6x\right).

Final Answer

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