" If "y=(1)/(a-z)" then find "(dz)/(dy)

If y=(1)/(a-z) , then (dz)/(dy)=

If y=1/(a-z), " then " (dz)/(dy) is

If y= (1)/(a-z) , then (dz)/(dy) is …............ .

If y= (1)/( a-z) , show that (dz)/( dy) = (z-a)^(2)

Suppose that z=ye^(x^2) where x = 2t and y = 1 then find (dz)/(dt)

If x=(1)/(z), y=f(x) and (d^(2)y)/(dx^(2))=kz^(3)(dy)/(dz)+z^(4)(d^(2)y)/(dz^(2)) , then the value of k is -

If y=sin^(-1)x,z=cos^(-1)sqrt(1-x^(2))," then: "(dy)/(dz)=

If U(x,y,z) =(x^(2) + y^(2))/(xy) + 3z^(2)y , find (del U)/(dx) + (del U)/(dy) + (del U)/(dz)

If U(x,y,z) = log(x^(3) + y^(3) +z^(3)) find (del U)/(dx) + (del U)/(dy) + (del U)/(dz)
