WebThe Partial Derivative Suppose we have a function of 3-variables: f (x,y,z). Then the partial derivative of f with respect to x is writen: [Equation 1] The partial derivative means the rate of change. That is, Equation [1] means that the rate of change of f (x,y,z) with respect to x is itself a new function, which we call g (x,y,z). WebThe chain rule of partial derivatives is a technique for calculating the partial derivative of a composite function. It states that if f(x,y) and g(x,y) are both differentiable functions, and y is a function of x (i.e. y = h(x)), then: ∂f/∂x = ∂f/∂y * ∂y/∂x; What is the partial derivative of a function?
