WebFirst Partial Derivative. In the context of mathematics, a partial derivative of a function is a different variable, and its derivatives concerning one of that variable quantity, where the others are held to be as constants. Partial derivatives are used in Differential Geometry and vector calculus. WebApr 18, 2015 · A standard example is the function f ( x) = x 2 sin ( 1 x) which is differentiable but its partial derivative with respect to x f ′ ( x) = 2 x sin ( 1 x) − cos ( 1 x) is not continuous. For the other direction let f: R n → R have continuous partial derivatives on a neighbourhood U of p. Define a linear function
