First partial derivative
WebA partial derivative is defined as a derivative in which some variables are kept constant and the derivative of a function with respect to the other variable can be determined. How to represent the partial derivative of a … WebJacobian matrix and determinant. In vector calculus, the Jacobian matrix ( / dʒəˈkoʊbiən /, [1] [2] [3] / dʒɪ -, jɪ -/) of a vector-valued function of several variables is the matrix of all its first-order partial derivatives. When this matrix is square, that is, when the function takes the same number of variables as input as the ...

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
