Prove that : 2 cos theta= sqrt (2+ sqrt(2+2 cos 4 theta)) .

Show that sqrt(2+sqrt(2 +2 cos 4 theta))= 2 cos theta

Prove that: sqrt(2+sqrt(2+2cos4 theta))=2cos theta

Prove that sqrt(2+sqrt(2+sqrt(2+2 cos 8 theta)))=2 cos theta

Show that sqrt(2+sqrt(2+sqrt(2+2cos 8theta)))=2cos theta

Show that sqrt(2+sqrt(2+sqrt(2+2cos 8theta)))=2cos theta

If 2 cos theta = sqrt3, cos theta xx tan theta = ?

If sin theta+cos theta=sqrt(2) and b=(sqrt(2)(sin theta+cos theta))/(sin theta cos theta), then 'b'is equal to

If cos theta-sin theta=sqrt(2)sin theta then Prove that cos theta+sin theta=sqrt(2)cos theta

If cos theta + sin theta =sqrt(2) cos theta prove that cos theta -sin theta =sqrt(2) sin theta
