In this video, I showed how to use Cramer's Rule to solve a system of Linear Equations

You could mention when Cramer's rule is possible and that every consistent system of equations can be reduced to form where Cramer's rule is possible Yes such series of videos is good idea

The most important rule of all is to watch Prime Newtons! 🎉😊

I heart Cramer's Rule. Disadvantage: it's slow for large matrices. Advantage: it doesn't introduce scads of inaccuracies when you try to program it. Gaussian Elimination involves lots of divisions throughout the process, which leads to inexact results. Cramer doesn't involve any divisions except at the final step.

There are divisionless determinant algorithms Some of them needs O(n^4) time but hey it is still polynomial time In fact next order of magintude of complexity is exponential complexity O(n^4) is slower than O(n^3) but not as much as O(2^n)

@@holyshit922Well, sure: the determinant itself doesn't involve any division. Cramer's Rule means calculating two determinants and done one division at the end.

Your videos are fantastic! Whenever I struggle with a concept, they always help me out. Do you have a video on finding the inverse using Cramer's rule, using adjugate?

Sir, your explanation is nice.. Why don't you add some other videos like Cayley Hamilton theorm and applications and diagonalization with applications to this matrix playlist...
