Sorry about the crummy format.
I've found matrix inverses before, but I am unsure of how to solve for these values. I would think that making the variables pivots would be the only way to find a solution, but I don't want to be taking shots in the dark. Any help would be much appreciated. Thanks
Nonsingular? I'm not sure what you mean by that. As for the determinant, I'm kind of vague. CD-BA is it? Then you'd need to make some sort of partition, wouldn't you?
I'm sorry, I find my math teacher very hard to follow. It's very hard for me to pick this stuff up.
Non-singular means has an inverse. Singular means does not have an inverse.
