Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(cos(x)sin(x))dx. Simplify \cos\left(x\right)\sin\left(x\right) into \frac{\sin\left(2x\right)}{2} by applying trigonometric identities. Take the constant \frac{1}{2} out of the integral. Divide 1 by 2. We can solve the integral \int\sin\left(2x\right)dx by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that 2x it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part.
