2cos theta=sqrt(2)+sqrt(2+sqrt(2+2cos theta theta))

If sqrt(2)cos theta=sqrt((2+sqrt(2+sqrt(2)))/(2)) then theta is

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

sqrt(2+sqrt(2+sqrt(2+2 cos 8 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

Prove that sqrt ( 2 + sqrt (2 + sqrt (2 + 2 cos 8 theta))) = 2 cos theta, where theta in [ (-pi)/(8), (pi)/(8)]

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

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

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