If I said 2y-2x=1 and I said find the derivative wrt. x, you would think that it is easy. Solve for y and take the derivative: dy/dx=1. Now I say, "take the derivative before solving for y ... 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. forex bullish
