For all `theta` in `[ 0, pi//2]`, show that `cos ( sin theta) gt sin (cos theta)`.

For all theta in [0,pi] , show that cos (sin theta) ge sin (cos theta) .

For all values of theta in[0,(pi)/(2)], show that cos(sin theta)>=sin(cos theta), show that

If sin (pi cos theta) = cos (pi sin theta). Find sin (2 theta)

The number of values of theta in (0, pi] , such that (cos theta + i sin theta) (cos 3 theta + i sin 3 theta) (cos 5 theta + i sin 5 theta) (cos 7 theta + i sin 7 theta) (cos 9 theta + i sin 9 theta) = -1 is

If sin(pi cos theta)=cos(pi sin theta),then sin2 theta=

If sin(pi cos theta)=cos(pi sin theta), then sin2 theta=

cos theta+sin theta=cos2 theta+sin2 theta
