Nettet30. nov. 2024 · Using the equality cos x = D x ( sin x) we can see that the integral ∫ sin 2 x ⋅ cos x d x is equal to integral ∫ sin 2 x ⋅ D x ( sin x) d x. That is ∫ sin 2 x ⋅ cos x d x = ∫ sin 2 x ⋅ D x ( sin x) d x Now we can apply the formula of 'integration by parts' NettetExpand the Trigonometric Expression sin(2x)cos(3x) Apply the sine double-angle identity.

Nettet14. jul. 2016 · Hint: sin 2 ( x) cos ( 4 x) is an even function, hence it has a Fourier cosine series involving cos ( n x) for n ∈ { 0, 1, 2, 3, 4, 5, 6 }. For any n ∈ N, ∫ cos ( n x) d x = C + sin ( n x) n. Actually: sin 2 ( x) cos ( 4 x) = − 1 4 cos ( 2 x) + 1 2 cos ( 4 x) − 1 4 cos ( 6 x). Can you finish from here?
