Super fast x Super slow 👍
It only works when there is no Negative numbers
Why is the answer different from the calculator
Thank you for the video. just had 2 questions. 1. after the trasnpose of A why do we need to copy the firt 2 colomns? 2. can this work on 4x4 matrix.
It’s Sarr’s rule, finding the cofactor matrix then taking the transpose
I am a freshman who has just learned linear algebra, and I am very curious about what principles it contains and whether there are any exceptions to this algorithm.
gaussian jordan method is easier tbh
The main difference is that Gauss-Jordan requires more thought in eliminating numbers step by step, whereas my fast algorithm follows a formulaic approach, making the process more systematic. Although it still involves calculating a 3x3 determinant, the steps are more structured, reducing the need for decision-making during the process.
Me too I thought that way, 😂@@hottomjack
this is just straight up wrong
Frrrrrr waste of time
Please explain what you think is wrong, otherwise your comment doesn't hold any value.

Is it easy? It is much easier to use the traditional method

Is it real?
Ofc
