How does invertible matrix work
WebBut for now it's almost better just to memorize the steps, just so you have the confidence that you know that you can calculate an inverse. It's equal to 1 over this number times this. a times d minus b times c. ad minus bc. And this quantity down here, ad minus bc, that's called the determinant of the matrix A. WebYou can check your work by multiplying the inverse you calculated by the original matrix. If the result IS NOT an identity matrix, then your inverse is incorrect. If A is the matrix you …
