Jacobian

1 9.6
Relating to the matrix of first partial derivatives in calculus
  • adjective
  • /dʒəˈkoʊbiən/
  • Specialized
: jacobiano
  • In calculus, the Jacobian determinant helps determine how transformations affect volume.

Examples

  • The Jacobian matrix is essential for analyzing the behavior of multivariable functions.

  • Non-local coupling specifically affects the Jacobian calculation, which in turn affects the convergence of the model and increases computational time.

    Academic text (2018)

  • To compute the stability of a system, we need to evaluate the Jacobian at the equilibrium points.

Jacobian positive

Morphology

Jacobian = Jacobi (opaque) = Jacobi + an

Formally derived from the surname 'Jacobi' with the adjectival suffix '-an'; the eponymous formation does not transparently convey the mathematical meaning to general learners.

Etymology

Jacobian comes from the name of the 19th-century mathematician Jacobi, so it means 'of Jacobi'. That's why the adjective Jacobian describes the matrix or determinant he studied, things that show how a function changes.
