In this unit we will explain the steps used in an effective word problem solving strategy then apply each step to solve sample word problems. When you finish this unit, you will be able to: – explain the steps used in an effective word problem solving strategy – apply each step to solve sample word…

In this particular example we’re given an equation that describes the result of operating on the arbitrary vector x = [x1; x2; x3] with the linear transformation T. Our job is to find the matrix representation of the linear transformation.…
