Learn how to solve one-variable linear equations problems step by step online. Solve the trigonometric integral int(sin(x)^2)dx. Rewrite the trigonometric expression \sin\left(x\right)^2 inside the integral. Take the constant \frac{1}{2} out of the integral. Simplify the expression inside the integral. We can solve the integral \int-\cos\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.
