If sin x cosh y = cos theta, cos x sinh y = sin theta then sinh^2 y =

If sin x cosh y = cos theta, cos x sinh y = sin theta then sinh ^ (2) y =

IF sin x cos h y= cos theta, cos x sin h y= sin theta and 4 tan x=3 .Then, sinh^2y=

If sin x sinh y = cos theta, cos x coshy = sin theta then cosh^2 y + cos^2 x=

If sin x sin h y = cos theta and cos x cos h y = sin theta then cos h^(2) y + cos^(2)x =

If sec theta cos h y= cosec x and cosec theta sinh y = sec x, then sinh^2y=

If sin alpha cos h beta = cos theta and cos alpha sin h beta= sin theta , then prove that sinh^(2)beta= cos^(2)alpha .

If x=cos theta-cos2 theta,y=sin theta-sin2 theta then (dy)/(dx) is

If x=sin theta-theta cos theta , y=cos theta+theta sin theta then (d^(2)y)/dx ^2=
