Please help. I always have a hard time with Linear Algebra. What's the difference between mapping from R3 into R2 and mapping from R2 into R3? Why is the following not a linear transformation from R3 into R2? L(x) = (1 + x1, x2)^T And why is this one not a linear transformation from R2 into R3? L(x) = (x1, x2, 1)^T Th
