WebCos2x formula can be used for solving different math problems. Let us consider an example to understand the application of cos2x formula. We will determine the value of cos 120° … WebExample 1: Integration of Sin2x dx from 0 to pi/2. Integration of sin2x dx from 0 to pi/2 can be written as: ∫ 0 π 2 s i n 2 x d x. This is the definite integral of sin2x with lower limit 0 and upper limit π/2. We know that, ∫ sin2x dx = - (½) cos2x + C. So, ∫ 0 π 2 s i n 2 x d x = [ − ( 1 2) c o s 2 x] 0 π 2. painshill car park
