If (cos3x)/(cos x)=(1)/(3) for some angle x,0<=x<=pi/2 then the value of (sin3x)/(sin2x) for some x is

IF (cos3x)/(cos x)=(1)/(3) for some angle x, then the value of (sin3x)/(sin x) for some x, is

If (cos3x)/(cosx)=1/3 for some angle x,0<=x<=pi/2 then the value of (sin3x)/(sinx) for some x is

If (cos3x)/(cosx)=1/3 for some angle x,0<=x<=pi/2 then the value of (sin3x)/(sin2x) for some x is

If cos3(x)/(cos x)=(1)/(3) then sin3(x)/(sin x) is

cos3x-cos2x=sin3x

cos3x-sin2x=0

If sin x+sin y=sqrt(3)(cos y-cos x) then (sin3x)/(sin3y)=

Some examples Type: 1 (1) (sin5A-sin3A)/(cos5A+cos3A)=tan A(2)(sin3x+sin x)sin x+(cos3x-cos x)cos x=0 (3) Prove that cot4x(sin5x+sin3x)=cot x(sin5x-sin3x)
