Matrices: Find the standard matrix of T for R2--R2 is a horizontal shear transformation that leaves e1 unchanged and maps e2 int e2 + 2e1, where e1 = (1,0) and e2 = (0,1). I really just need a start on how to go about this, I'm pretty confused...

I can try to help as i'm in this class but i believe you are farther than us, does e2 stand for elementary matrices?

I figured it out, you need to turn e2 into e2 +2e1, and then that's pretty much it
