If `sin5theta=5sintheta-20sin^3theta+ksin^5theta` then the value of k is

If sin5 theta=5sin theta-20sin^(3)theta+k sin^(5)theta then the value of k is

sin5theta+sin3theta+sintheta=0

sintheta+sin2theta+sin4theta+sin5theta=0

5sintheta.sin8theta=

prove sin(5theta) = 16sin^5(theta)-20sin^3(theta)+5sin(theta)

If sintheta+sin3theta+sin5theta=0,0lethetale(pi)/(2) then theta =

If theta be any real, prove that : sin5 theta= 5sin theta-20 sin^3 theta+16 sin^5 theta .

If sintheta+sin5theta=sin3thetaand0lttheta((pi)/(2)) , what is the value of theta (in degrees) ?

If tan(theta + 3theta) tan (2theta + 3theta)=1 , then the value of sin(5theta - 2theta) is:

If 5 sin theta-4 cos theta=0, 0^@ < theta<90^@ , then the value of (5sin theta-2 cos theta)/(5sin theta+3 cos theta) is:
