If `x^2 = y^x` then `dy/dx = `

If y sec x+ tan x +x^2 y=0 , then (dy)/(dx) =

If 2^x-2^y=2^(x+y) then dy/dx= (a) (2^x+2^y)/(2^x-2^y) (b) (2^x+2^y)/(1+2^(x+y)) (c) (2^(x-y))(1-2^y)/(2^x+1) (d) (2^x-2^y)/(2^x+2^y)

If x^2+y^2=x-y find dy/dx

If x^(2) = e^(x-y) , then (dy)/(dx) at x = 1 is ……..

If y=2^(-x) then (dy)/(dx)=

If x ^(2) + y ^(2) = sin ( x + y), then (dy)/(dx) =

If x^(y) = 2^(x-y) , then (dy)/(dx) =?
