If `tan(x/2)=cosec x - sin x` then the value of `tan^2(x/2)` is

If tan(x/2)=cosec x-sin x , then find the value of tan^(2) (x/2) .

If tan(x/2)=cosec x-sin x , then tan^(2)(x/2) is equal to

If tan(x/2)=cosec x-sin x" then (1+sec^(2)(x)/(2))^(2)=

If 2 tan ^(-1)(cos x )=tan ^(-1)(2 cosec x), then the value of x is

If sin2x=n sin 2y , then the value of (tan(x+y))/(tan(x-y)) is :

If sin 2 x=n sin 2 y then the value of (tan (x+y))/(tan (x-y))=

If tan^4 x-tan^2 x=1 , then the value of sin^4 x+Sin^2 x is: यदि tan^4 x-tan^2 x=1 , तो sin^4 x+Sin^2 x का मान है:
