Question

The Jacobian and Hessian are key concepts related to gradients and curvature in multidimensional functions. Which of the following statements is correct?

A Jacobian is a first order partial derivative. Hessian is a second order partial derivative of a function.
B Hessian is a first order partial derivative. Jacobian is a second order partial derivative of a function.
C Jacobian is a single spherical integral. Hessian is a double spherical integral of a function.
D Hessian is a single spherical integral. Jacobian is a double spherical integral of a function.

Explanation

A Jacobian collects first-order partial derivatives, while a Hessian collects second-order partial derivatives and describes local curvature of a multivariable scalar function.
