Maple can find the inverse of a matrix a lot quicker than we can by hand! We did p. 77 number 10 via the Gauss-Jordan method. Now let's do it on Maple:
Check your notes to see that this is the same answer that we got in class via the Gauss-Jordan method of finding an inverse.
To find the product of two matrices (for Maple 6 users, all of these commands are different!), first we define the matrices, and then use Maple's commands to multiply.
Let's check that A and B from above are really inverses of each other:
> evalm(A&*B); evalm(B&*A);
So, they are inverses.
