⚠️ Inverse of 5x5 matrix: but not using determinants! ✅

We use the Gauss-Jordan method to find the inverse of a 5x5 matrix, avoiding determinants.

Learned this in engineering math. Forgot it since and now its popped up in my FEM class. Now I see why we were taught this. Very helpful!

Hallo David!, the voice and music are too inspirate to discover maths... hug from Paraguay!

I have a test coming up, and I have to say that you make math so relaxing jajaaja

Appreciate you putting this out. Thanks a lot

Cool movies You make 👌 I found Your channel already today 😲

I was never taught the determinant method to find inverses. I can see why, because the Gauss-Jordan is so much simpler and less error prone.

Have an exam tomorrow, was finding ways to find 7*7 inverse ! THANK YOU SIR for making me put this appreciating comment ❤️ love

I really love your videos, and I needed a favor. I need you to prove a bunch of things for me. I need you to prove the commutative property of addition for all real numbers, the multiplication of fractions, the addition of fractions, the commutative property of multiplication for all real numbers, and the distributive property for all real numbers including irrational numbers please. What I love about math is that it is always consistent and that properties are not made from thin air, and if you prove all these properties for me I will feel much better about that fact.

Please I have searched in so many places and never found a satisfying answer. Please out of the kindness of your heart answer my questions

At 2:03, Why have ve just multiplied the diagonal members to find out determinant. I thought it was only qpplicable when all the elements of matrix but diagonal elements are zero. But here a34 is not zero.?

Yh but this was quicker cz the matrix A is really close to the identity, try it with a matrix with no 0 entries and you will see it takes the same amount of time to row reduce it till the identity
