First partial derivative
WebLecture 9: Partial derivatives If f(x,y) is a function of two variables, then ∂ ∂x f(x,y) is defined as the derivative of the function g(x) = f(x,y), where y is considered a constant. It is called partial derivative of f with respect to x. The partial derivative with respect to y is defined similarly. We also use the short hand notation ...

WebExample 1. Let f ( x, y) = y 3 x 2. Calculate ∂ f ∂ x ( x, y). Solution: To calculate ∂ f ∂ x ( x, y), we simply view y as being a fixed number and calculate the ordinary derivative with respect to x. The first time you do this, it might be easiest to set y = b, where b is a constant, to remind you that you should treat y as though it ...
