`(cos 3theta)/(2cos 2theta-1)=(1)/(2)` if

(cos3theta)/(2cos2theta-1)=(1)/(2) if

(cos3 theta)/(2cos2 theta-1)=(1)/(2) if (n in1)

1+cos theta=2cos^(2)theta

If theta=(pi)/(8) , then what is the value of (2cos theta+1)^(10)(2cos2theta-1)^(10)(2cos theta-1)^(10)(2cos4 theta-1)^(10) ?

Prove that : (2 cos 2^n theta +1)/(2cos theta +1)= (2cos theta-1)(2cos 2 theta-1) (2cos 2^2 theta-1)............ (2cos 2^(n-1)theta-1) .

Prove that: (2cos2^(n)theta+1)/(2cos theta+1)=(2cos theta-1)(2cos2 theta-1)(2cos2^(2)theta-1)...(2cos2^(n-1)theta-1)

Prove that: (2cos2 theta+1)/(2cos theta+1)=(2cos theta-1)(2cos2 theta-1)(2cos2^(2)theta-1)...(2cos2^(n-1)theta-1)

Prove that : (2 cos 2^n theta + 1)/(2 cos theta +1) = (2 cos theta -1) (2 cos 2theta -1) (2 cos 2^2 theta -1) … (2 cos 2^(n-1) theta -1)

Prove that : (2 cos 2^n theta + 1)/(2 cos theta +1) = (2 cos theta -1) (2 cos 2theta -1) (2 cos 2^2 theta -1) … (2 cos 2^(n-1) theta -1)
