=== Comparison to Jacobian Matrices ===

A [[Calculus/JacobianMatricesAndDeterminants|Jacobian matrix]] is also a square matrix of partial derivatives. Importantly however, it is formed by the first-order derivatives of a vector-valued function, such as a [[Calculus/ParametricEquation|parameterized]] function.
