Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(cos(4x)cos(6x))dx. Rewrite the trigonometric expression \cos\left(4x\right)\cos\left(6x\right) inside the integral. Take the constant \frac{1}{2} out of the integral. Expand the integral \int\left(\cos\left(10x\right)+\cos\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\cos\left(10x\right)dx results in: \frac{1}{20}\sin\left(10x\right).
