Nettet6. apr. 2024 · Definite Integration of sinx A definite integral is an area under a curve between two fixed limits. The process of finding integrals is called integration. Definite integrals are used when the limits are defined to generate a unique value. We apply the formula of definite integrals [latex] {\int}^ {b}_ {a}f (x)dx = f (b) - f (a) [/latex] NettetCalculus Find the Integral (sin (x))^2 sin2 (x) sin 2 ( x) Use the half - angle formula to rewrite sin2(x) sin 2 ( x) as 1−cos(2x) 2 1 - cos ( 2 x) 2. ∫ 1−cos(2x) 2 dx ∫ 1 - cos ( 2 x) …

NettetLet's look at the integral as follows: If u = sin x and d v = sin x d x, then d u = cos x d x and v = − cos x. So we have ∫ sin 2 x d x = u v − ∫ v d u = − sin x cos x + ∫ cos 2 x d x If we add ∫ sin 2 x d x to both sides, we get: ∫ sin 2 x d x + ∫ sin 2 x d x = − 1 2 sin 2 x + ∫ 1 d x = − 1 2 sin 2 x + x + C and so NettetYou cannot directly integrate sin^2 (x). Use 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.
