If `x=(1-sqrty)/(1+sqrty` then `(dy)/(dx)=`

Find by the definition the differential coefficient of the following: If x=(1-sqrty)/(1+sqrty) prove that dy/dx=(4(x-1))/(x+1)^3

If sqrtx + sqrty = sqrta " then " (dy)/(dx) = ?

if sqrtx+sqrty=4 , then (dy)/(dx) is :

sqrtx + sqrty = sqrta " then " (dy)/(dx) = ……..

If sqrtx+sqrty=2 , then what is (dy)/(dx) at y = 1 and x = 1 equal to ?

If sqrtx+sqrty=4, then dy/dx is

If y=sqrt(x+sqrt(y+sqrt(x+sqrty+...oo))) then (dy)/(dx) equal to

Find the derivatives of the function If x = log (1 + sqrty), then show that (dy)/(dx) = 2 sqrtye ^(x)

If sqrtx + sqrty = sqrtx , find (d^2y)/(dx^2) at x = a

If sqrtx+sqrty=1 , then dy/dx at (1/4,1/4) is
