We continued our use of inverse matrices today. We will be using them to solve sytems of equations. The process is as follows:1) Set up matrix equation similar to above
2) Find the inverse of the square matrix
3) Multiply on the left time the column matrix
See a video demonstration here. We practiced on a worksheet in class, then students worked on the graded assignment.
Homework:
p. 233 #'s 12-30 even, (#32 & #46 extra credit)
