Hence, ... Solution: To find the integral of sin^2x, we will use its formula sin^2x = (1 - cos2x)/2 to simplify the problem. ∫ sin^2x dx = ∫[(1-cos2x)/2] dx
Nettet24. mar. 2015 · To compute the integral I = ∫ sin ( 2 x) cos ( 2 x) d x , there is two possible ways. the first one : use sin ( 2 a) = 2 sin ( a) cos ( a) and so, I = 1 2 ∫ sin ( 4 x) d x = − 1 2 × 1 4 cos ( 4 x) + C = − 1 8 cos ( 4 x) + C the second one : change variable u = sin ( 2 x), d u = 2 cos ( 2 x) d x and so I = 1 2 ∫ u d u = u 2 4 + C = 1 4 sin 2 NettetThe integral cosine formula is: \displaystyle \int \cos u \cdot du = \sin u ∫ cosu ⋅ du = sinu Let’s see some examples for cosine integrals. Example 1. Integral of cos2x \displaystyle \int \cos (2x) \ dx= ∫ cos(2x) dx = We substitute the 2x 2x for u u, we derive and we pass dividing the 2 2:
NettetWe have to find the integral of y = (cos x)^2 - (sin x)^2. We know that cos 2x = (cos x)^2 - (sin x)^2 => y = cos 2x Int [ cos 2x dx] let 2x = y, dy/2 = dx => Int [...
