Integral of cos 2x and sin 2x
NettetThe integral of cos2x can be easilty obtained using the formula ∫cos(ax + b) dx = (1/a) sin(ax + b) + C. Therefore, the integral of cos2x is given by ∫cos 2x dx = (1/2) sin 2x + … 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
