`cos A cos 2A cos 4A..........cos 2^(n-1) A`

cos A cos2A cos4A......cos2^(n-1)A

Prove that : cos A cos 2A cos 2^2 A cos 2^3 A........ cos 2^(n-1) A= (sin 2^n A)/(2^n sinA) .

Prove that cos A cos 2A cos 2^(2) A cos 2^(3)A....cos 2^(n-1) A=(sin 2^(n) A)/(2^(n) sin A)

cos A cos 2A cos4 A…… cos2^(n-1) A equals

Prove that: cos A cos 2A cos 2^(2)A cos 2^(3)A….....cos 2^(n-1)A=("sin" 2^(n)A)/(2^(n)"sin"A) .

Simplify the product cos A cos 2A cos2^2A……cos2^(n-1)A

If n=1,2,3,......, then cos alpha cos2 alpha cos4 alpha.........cos2^(n-1)alpha is equal to

Using Principle of Mathematical Induction, prove that : cos alpha cos 2 alpha cos 4 alpha ............. cos (2^(n-1) alpha)= (sin (2^n alpha))/(2^n sin alpha) for all n in N.

If (2^n+1)theta=pi then 2^n costheta cos2theta cos2^2 theta .......cos 2^(n-1) theta=
