Given p sin x + q cos x, divide the expression by p 2 + q 2 to get a sin x + b cos x for a 2 + b 2 = 1. Now name a = cos α and b = sin α . Notice that what you got is


Formula of trignometric is Sin(2x)=2sinx.cosx then The value of 2sin(x/2).cos(x/2) is Substitute x/2 in place of x in formula Then sin (x)=2sin(x/2).cos(x/2)

Use the identity 2 sin x cOs x = sin (2x) to find the power series expansion of sin x at x = 0. (Hint: Integrate the Maclaurin series of sin (2x) term-by-term.) n=0. fullscreen. check_circle.
