How do you find the inverse of a matrice? My mind is almost dead from finals study and reading or seraching online for how to do it is killing me.

Is there a simple way to do it?:psyduck:

This is the second...or third thread you have made that has been found after fifteen seconds of Google searching. If the next thread you make is asking a question that can be found in an amazingly short span of time on Google, I will take your thread posting privileges away.
