Jacobian
- noun
- /dʒəˈkoʊbiən/
- Specialized
- This parallel parallelotope goes by G into this one, and its volume is the Jacobian, which is the determinant of G.
Examples
-
So the determinant of the Jacobian is independent of the frame.
-
In calculus, the Jacobian helps us understand how functions change in multidimensional space.
-
The determinant of the Jacobian is independent of the frame.
-
This parallel parallelotope goes by G into this one, and its volume is the Jacobian, which is the determinant of G.
Synonyms
A number calculated from a square grid of numbers that helps solve many equations

Morphology
Jacobian = Jacobi (opaque) = Jacobi + an
Eponymous derivation from 'Jacobi' + '-an'; the name-based formation does not transparently indicate the specific concept of a determinant measuring area/volume change.
Etymology
Jacobian comes from the name of the mathematician Jacobi, so it means 'of Jacobi'. In calculus the Jacobian (the determinant of that matrix) measures how much an area or volume stretches or shrinks under a change, which explains its modern use.
