" (a) "cos2 theta=cos^(2)theta

The solution of cos2theta=cos^(2)theta is:

The solution of cos2theta=cos^(2)theta is:

The solution set of cos 2 theta = cos^(2) theta is

Range of f(theta) = cos^(2) theta(cos^(2) theta + 1) + 2 sin^(2) theta is

If theta = pi/(2^(n) + 1), "show that",2^(n) cos theta cos 2 theta cos2^(2) theta cos2^(3) theta.... cos2^(n-1) theta = 1.

If (2^(n)+1)theta=pi then 2^(n)cos theta cos2 theta cos2^(2)theta......cos2^(n-1)theta=

The solution set of cos2theta=cos^(2)theta-sin^(2)theta is …………

If theta=pi/(2^n+1) then cos theta cos 2 theta cos 2^(2) theta...... Cos2^(n-1) theta is equal to

Using induction,prove that cos theta cos2 theta cos2^(2)theta...cos2^(n-1)theta=(sin2^(n)theta)/(2^(n)sin theta)

If theta =(pi)/(2 ^(n) +1), then cos theta cos 2 theta cos 2^(2) theta …cos 2 ^(n-1)theta is equal to
