WebSin2x is a popular trigonometry identity. Trigonometry, as it suggests, is all about triangles, mostly right-angled triangles. It is a system that helps us to work out missing or unknown side lengths or angles in a triangle. Sine, Cosine & Tangent are some of the functions used for finding the sides of a triangle with their given universal values. WebUse trigonometric identities and calculus substitution rules to solve the problem. 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. Set u = 2x and du = 2dx to perform u substitution on the integral. Since dx = du/2, the result is 1/4 times the ...
