Inverse of 4x4 Matrix (fx-570ES)

Kindly watch this video for clearer explanation 👉 • Inverse of 4x4 matrix ...
Trick in using Casio fx-570ES calculator. A faster way to obtain the adjoint, adjugate or adjunct of the transpose of a 4x4 (4 by 4) matrix. I believe this method is faster in obtaining the inverse matrix of a 4 by 4 matrix compared to manual calculation and most importantly it won't affect our marks as steps are included. Worth to try :)

Better explanation and guidelines 👉 kzbin.info/www/bejne/f6vUdomgp5hso6s, and I personally think that this video has a better vocal as compared to the above video. Thanks for watching and have a nice day.

We can do it by row operation. Reduce the matrix and its identity matrix to rref.

[@ahsingtv]

Yes, that's one of the methods. Thanks for watching and have a nice day.

DUDEEE. YOU JUST MADE GETTING THE DETERMINANT OF A 4X4 A WHOLE LOT EASIER!!! THANK YOU SO MUCH

[@ahsingtv]

My pleasure. Thanks for watching and have a nice day.

[@Leo-di9fq]

Straight to the point! nice work

[@ahsingtv]

Thanks! Thanks for watching and have a nice day.

[@jettyroy]

That's actually helpful. Thanks!

[@ahsingtv]

My pleasure. Thanks for watching. Have a nice day.

[@asganawayaway]

what if the determinant is 0? I cannot find the inverse

[@ahsingtv]

Hi Michele. When determinant = 0, the matrix has no inverse. Thanks for watching and have a nice day.

@@ahsingtv thank you, the video is super good by the way Thank you for making it was very helpful 👍🏼

[@ahsingtv]

My pleasure. Thank you very much!

[@ninex9631]

I don't understand the 1/det A x adj A^T What does it mean how do you calculate that

[@ahsingtv]

Hi, the inverse is equal to 1 over determinant multiply adjoint. I think this video is clearer kzbin.info/www/bejne/f6vUdomgp5hso6s, hope it helps.

Hi, vivek. Sorry, but I couldn't get you. How may I help you?

[@ninex9631]

Also by the way How to deal with cramers matrix 4 by 4 with parameter?

[@ahsingtv]

Hi Ninex. Currently, I only have examples up to 3 variables/unknowns: 1. 2 unknowns kzbin.info/www/bejne/oGSce3isZ5ytkJI 2. 3 unknowns kzbin.info/www/bejne/pJTYlH9vrpJgq9E 3. 3 unknowns kzbin.info/www/bejne/jGXNYX2gq6qWjdU If needed, may I have the question so that I can work out for you.

[@ninex9631]

@@ahsingtv thanks!! the problem I had is that I had matrix 4 by 4 (with parameter) it was multiplied by matrix (3 unknown because one number was given and it equaled to something We had to figure amount of solutions depending on parameter a It was only one of the tasks on exam ;_; The other one was I had matrix X times matrix 3 by 3 equaled to matrix 3 by 3 - X

[@ahsingtv]

🤔 can't imagine. Could you snapshot the question and post it here facebook.com/groups/292419116266033?
