int sin xsin3xdx=

Solve: 4sinxsin2xsin4x=sin3x

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

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

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

Solve 4sinx.sin2x.sin4x=sin3x

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

If f(x)=|(sin x+sin 2x+sin3x,sin2x,sin3x),(3+4sinx,3,4sinx),(1+sinx,sinx,1)|, then the value of int_0^(pi/2) f(x) dx is

sin2x+2sin4x+sin6x= 4cos^(2)xsin4x
