`sin3x+sin2x-sinx=4sinxcos(x/2)cos((3x)/2)`

Prove that: \ sin3x+sin2x-sin x=4sin xcos(x/2)cos((3x)/2)

Prove that : sin(3x)+sin(2x)-sinx=4sinxcos((x)/(2))cos((3x)/(2))

Prove that: sin 3x + sin 2x - sin x = 4 sin x cos x/2 cos (3x)/2

Prove that: (i) sin 3x+"sin" 2x-"sin" x = 4 sin x cos((x)/(2))cos((3x)/(2)) (ii) ("sin" 3x+"sin" x)"sin" x+(cos 3x-cos x)cos x=0.

Prove the following Identities sin x +sin 2x + sin 4x +sin 5x = 4 cos(x/2).cos((3x)/2)sin3x

sin 3x + sin 2x - sinx = 4sin x cos "" x/2 cos "" (3x)/(2)

Prove that sin 3x + sin 2x - sin x = 4 sin x cos ""(x)/(2) cos "" ( 3x )/(2)

sin 3x + sin 2x - sin = 4sin x cos "" x/2 cos "" (3x)/(2)

sin 3x + sin 2x - sin = 4sin x cos "" x/2 cos "" (3x)/(2)

sin 3x + sin 2x - sin = 4sin x cos "" x/2 cos "" (3x)/(2)
