`int sin x sin2x sin3x`

sin x sin 2x sin 3x

The value of the definite integral int_(0)^(pi//2)sin x sin 2x sin 3x dx is equal to

int_(0)^(pi//2)sinx sin2x sin3x sin 4x dx=

Solve 4 sin x sin 2x sin 4x = sin 3x .

Solve the following integration int(sin 2x+sin 5x-sin 3x)/(cos x+1-2 sin^(2)2x)dx

If f(x)= =|{:(sinx+sin2x+sin3x,sin2x,sin3x),(3+4sinx,3,4sinx),(1+sinx,sinx,1):}| then the value of int_(0)^(pi//2) f(x)dx , is

Evaluate: (i) int(sin2x)/(sin5xsin3x)\ dx (ii) int(1+cotx)/(x+logsinx)\ dx

int(sin2x)/(sin5xsin3x)dx is equal to

Evaluate: int(sin2x)/(sin5xsin3x)dx

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