^{2024 Integral cos 2 - What is the integral of #int sin^2 (x).cos^2 (x) dx #? Calculus Introduction to Integration Definite and indefinite integrals. 1 Answer} ^{To find the integral of cos 2 x, we use the double angle formula of cos. One of the cos 2x formulas is cos 2x = 2 cos 2 x - 1. By adding 1 on both sides, we get 1 + cos 2x = 2 cos 2 x. By dividing by both sides by 2, we get cos 2 x = (1 + cos 2x) / 2. We use this to find ∫ cos 2 x dx. Then we get. ∫ cos 2 x dx = ∫ (1 + cos 2x) / 2 dx. Evaluate the Following Integrals: ∫ Cos { 2 Cot − 1 √ 1 + X 1 − X } D X . CBSE Science (English Medium) Class 12.
