If `y=x^0` , then `dy/dx =`

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

If x^(3) +y^(3) +4x^(3) y=0 ,then (dy)/(dx)=

If sqrt(y+x)+sqrt(y-x)=c (where c!=0 ), then dy/dx

If x=e^(y+e^(y+e^y^(------ ∞))) , x>0 , then (dy)/(dx) is equal to (A) (x)/(1+x) (B) (1)/(x) (C) (1-x)/(x) (D) (1+x)/(x)

If x=e^(y+e^(y)+..... oo) , x >0 , then (dy)/(dx) is equal to........

If xsin y+ysin x =0,then (dy)/(dx) =

xsqrt(1+y)+ysqrt(1+x)=0 , then (dy)/(dx)=

If x^(4) +y^(4) +5x^(3) y=0then (dy)/(dx) =
