" If "2cos A sin B=x," then the value of "x" is "

If 2cos x+sin x=1, then find the value of 7cos x+6sin x

If sin(sin x+cos x)=cos(cos x-sin x), and largest possible value of sin xis(pi)/(k), then the value of k is

If sin x + sin y = a , cos x - cos y = b then the value of tan ((y-x)/2) is _______ in terms of a and b.

If sin x + sin^(2) x= 1 , then the value of cos^(8) x - cos ^(4) x + 2cos^(2)x -1 is equal to :

if sin x + sin^2 x = 1 , then the value of cos^2 x + cos^4x is

if sin x + sin^2 x = 1 , then the value of cos^2 x + cos^4x is

If cos x+ cos ^(2) x=1,. then the value of sin ^(2) x+ sin ^(4) x is

if sin x + sin^2 x = 1 , then the value of cos^2 x + cos^4x is
