int sinx/sin(3x) dx=

Solve: 4sinxsin2xsin4x=sin3x

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

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

int x.sin x dx

Prove that (cos3x)/(sin2xsin4x)+(cos5x)/(sin4xsin6x)+(cos7x)/(sin6xsin8x)+(cos9x)/(sin8xsin10 x) = 1/2(cos e cx)[cos e c2x-cos e c10x]

The integral int (sin^2xcos^2x)/(sin^5x+cos^3xsin^2x+sin^3xcos^2x+cos^5x)^2 dx is equal to
