Formula to Find sin2x sin ⁡ 2 x. The double angle identity of sinx sin ⁡ x can be obtained by using the sum formula of sin(A+B) sin ⁡ ( A + B ) .

This can be proved by adding formulae for sin(( n − 1) x + x ) and sin(( n − 1) x − x ) . Serving a purpose similar to that of the Chebyshev method, for the tangent we can write: How to integrate sin^2 x using the addition formula for cos(2x) and a trigonometric identity. Find the integral of sin^2 (X) As soon as you see a question asking you to integrate the square of sin, cos or tan, your first approach should be to use trigonometric identities and double angle formulas. For sin 2 (X), we will use the cos double angle formula: cos (2X) = 1 - 2sin 2 (X) In this case, sin(x) is the inner function that is composed as part of the sin2(x). To look at it another way, let's denote u = sin(x) so that u2 = sin2(x).

I tried: $(\sin^2(x))^2 = ((1-\cos2x)/2)^2$ but still getting $\cos x$ to the power of $2$. Wolframalpha only shows the answer which i have no idea how they got it. Could somebody help ?
