True-False, for Quiz 5 [B]

These are just for practice and don't affect your grade. I'm assuming you've read over Leon, Ch 4. For this quiz assume that:


True False. T(R2) = Col(C).

True False. Ker L is a subspace of V that depends on which basis is used for V.

True False. If T is a rotation, then its kernel is {0}, and C is singular.

True False. dim Ker T + dim range T = 2.

True False. If A and B are two matrix rep'ns of L, then A is similar to B.

True False. If Ker L contains a nonzero vector, then L is not 1-1.

True False. Let L2 (v) = L(L(v)).Then the matrix rep'n of L2 is C2.

True False. Any matrix rep'n of L must be square and nonsingular.

True False. If A is similar to B, then AT is similar to BT and A2 is similar to B2 (see HW).

True False. If B is similar to I then B = I.
