Putting x2=cos2θ, we have `y=tan^ (−1) ( (sqrt (1cos2θ)sqrt (1−cos2θ))/ (sqrt (1cos2θ)−sqrt (1−cos2θ)))` `y=tan^ (−1) ( (sqrt (2cos^2theta)sqrt (2sin^2θ))/ (sqrt (2cos^2θ)−sqrt (2sin^2θ)))` `y=tan^ (X^2y^2z^2=1 WolframAlpha Have a question about using WolframAlpha? Dividing 1 by 2 , we get =>y2/x2 = (1 tan a) / (1 tan a) =>y2 = x2 (1 tan a) / (1 tan a) differentiating both sides wrt x, we get, =>2y dy/dx = 2x (1 tan a) / (1 tan a) =>y dy/dx = x (1 tan a) / (1 tan a) => dy/dx = x (1 tan a)/y (1 tan
