Main Question or Discussion Point

hi, I always see that jacobian matrix is derived for just 2 dimension ( ıt means 2x2 jacobian matrix) in books while ensuring the coordinate transformation. After that kind of derivation, books say that you can use same principle for higher dimensions. But, I really wonder if there is a proof which ensure that jacobian matrix is compatible with higher dimensions???? I am asking because there are proofs which ensure the jacobian matrix only in 2 dimensions not higher dimensions.. Thanks in advance.... I am looking forward to your mathematical demonstrations....

Jacobian matrices have several useful properties.
For which one of those properties are you seeking a proof?

While doing integral in terms of space-time coordinates, and if you want to change coordinates, we should use jacobian matrix and determinant rule. I know the proof of why we should use jacobian determinant rule if there are 2 coordinates, but I do not know the proof of how this jacobian determinant rule fits with the higher dimensions or high order coordinates ????

The proof you are seeking is that of the 'change of variable formula for integrals using Jacobians'. It is long and complex and I expect it will only appear in fairly advanced vector calculus texts.

This Stack Exchange Q&A gives an intuitive overview of the proof (in the first answer) and also contains a reference to a text in which the full proof can be found (in the last answer).
