... T(a) - T(b) = 0. Thus, a - b is in the kernel of T, so a - b = 0. Hence, a = b which shows that T is one-to-one. Conversely, suppose that ker T … {0} say v is in ker T and v … 0. We then have T(v) = 0 = T(0) yet v … 0. Hence, T is not one-to-one. So if T is one-to-one, ker T = { 0}. We have seen tha ...

Math 416 Midterm 1. Solutions. Question 1, Version 1. Let us define
... But when we write it this way, it is clear that we can: adding the second row to the first puts this in RREF, and we will have three pivots. (We could work harder for the actual solution, but that is not needed here.) So now we need to find a subset that is a basis. Since we know that any basis of P ...
