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 ... WebConstant times x. Derivative is just that constant. If we took the derivative with respect to y, the roles have reversed, and its partial derivative is x, 'cause x looks like that constant. …
