" xiii."quad sin2 theta=2sin theta cos theta" for all "theta in R

If s=(sin^(2)theta+cos^(4)theta) for all theta in R, then

The expression cos 3 theta + sin 3 theta + (2 sin 2 theta-3) (sin theta- cos theta) is positive for all theta in

The expression cos 3 theta + sin 3 theta + (2 sin 2 theta-3) (sin theta- cos theta) is positive for all theta in

The expression cos 3 theta + sin 3 theta + (2 sin 2 theta-3) (sin theta- cos theta) is positive for all theta in

cos theta+sin theta=cos2 theta+sin2 theta

If sin2 theta = cos 3 theta then theta =

sin theta+sin2 theta+sin3 theta=1+cos theta+cos2 theta

If x=sin^(16)theta+cos^(20)theta, then for all theta in R

Simplify, costheta[[cos theta, sin theta],[-sin theta, cos theta]] + sin theta [[sin theta, -cos theta],[cos theta, sin theta]]

sin^(3)theta + sin theta - sin theta cos^(2)theta =
