The partial derivative of the function f (x,y) partially depends upon "x" and "y". So the formula for for partial derivative of function f (x,y) with respect to x is: ∂ f ∂ x = ∂ f ∂ u ∂ u ∂ x + ∂ f ∂ v ∂ v ∂ x. Simiarly, partial derivative of function f (x,y) with respect to y is: signal mountain veterinary clinic https://lisacicala.com
