linear algebra - shortcut for finding a inverse of matrix
Of course, if there's an expectation that the determinant is 1, then maybe it's appropriate. Also, be warned that the row/column operations are 'meaningful' (you see that they are computing the inverse) but the 'trick' is just blind application of a formula. $\endgroup$ –

Finding Inverse of a 4*4 matrix - Mathematics Stack Exchange
2020年6月14日 · $\begingroup$ The idea of replacing the values with $\sin(\pi/12), \cos(\pi/12), \dots$ seems like an interesting idea for the computation, since then the determinant will have terms like $\sin(\pi/12)\cos(\pi/12) = \frac{1}{2}\sin(\pi/6)$ (using the double angle formula). In terms of calculating the inverse, you can try Cramers rule, but I don ...
