Okay, so just pick a computer algebra system, or you can use a graph and calculator.
00:07
Just make sure that you know where to find this calculator, whether you're using google or...
00:12
Whoops, i accidentally hit the wrong one.
00:16
There we go, so that's the one i'm at.
00:19
And you can just type in your matrix exactly the way it looks, and it's a 3x3 matrix.
00:25
We're looking at 2 -1 -1 -1 -negative 3.
00:32
0 to 4 negative 6 0 and then you have to hit enter or save the matrix into your calculator somehow and then from here let me put it this way you would not want to multiply this matrix by itself five times because what you would have to do is 2 times 2 plus 1 times negative 3 plus 1 times 4 and that's just to get the first entry of a squared.
01:10
And you'd have to do that nine times just to get a squared.
01:14
And then you'd have to multiply a squared by a.
01:17
Again, you'd have to do that same process nine more times to get a cubed.
01:24
So let me put it this way.
01:26
You'd want to know how to use a calculator...
