Find the value of sqrt((1+cos theta)/(1-cos theta))+sqrt((1-cos theta)/(1+cos theta))

If x= a sin 2theta (1+ cos 2theta) , y= b cos 2theta(1- cos 2theta) , then (dy)/(dx) =

If x= a sin 2theta (1+ cos 2theta) , y= b cos 2theta(1- cos 2theta) , then (dy)/(dx) =

If x= a sin 2theta (1+ cos 2theta) , y= b cos 2theta(1- cos 2theta) , then (dy)/(dx) =

If x = (1-cos^2 theta)/(cos theta), y = (1-cos^(2n)theta)/(cos^n theta) then show that (dy/dx)^2 = n^2((y^2 + 4)/(x^2 +4))

If 2cos theta=x+1/x then 2cos^2 theta=

if sqrt(x)+(1)/(sqrt(x))=2cos theta then x^(6)+(1)/(x^(6))=
