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

If sinx=1/(3) , then the value of sin3x is

(sin3x-sinx)/(cos2x) =

The maximum value of 4sin^2x+3cos^2x+sinx/2+cosx/2 is

If sinx - cosx = 0, then the value of (sin^3 x-cos^3 x) is: यदि sinx - cosx = 0 ,तो (sin^3 x-cos^3 x) मान होगा :

(cos^3x-sin^3x)/(cosx-sinx)
