If `sintheta,tantheta,costheta` are in G.P. then `4sin^2theta-3sin^4theta+sin^6theta=?`

sin2theta-sin4theta+sin6theta=0

sin2theta+sin4theta=sin6theta

sintheta+sin2theta+sin4theta+sin5theta=0

sintheta+sin7theta=sin4theta

Solve 4sin theta sin2 theta sin4 theta=sin3 theta

If sintheta - costheta = 0 , then sin^4theta - cos^4theta = ?

Solve sin 6 theta=sin 4 theta-sin 2 theta .

If sintheta+costheta=1/2 then find the value of 16(sin2theta+cos4theta+sin6theta)

Show that costheta [[costheta, sintheta],[-sintheta, cos theta]] + sin theta [[sintheta ,-cos theta],[costheta, sin theta]] =1
