Sin2x, Double angle formulas are called so because they have 2 angles in the trigonometric functions. Practice examples of sin 2a to understand the concept better at BYJU'S.
Use the half angle formula, sin^2(x) = 1/2*(1 – cos(2x)) and substitute into the integral so it becomes 1/2 times the integral of (1 – cos(2x)) dx. Step 2 Set u = 2x and du = 2dx to perform u substitution on the integral. Since dx = du/2, the result is 1/4 tim...
