... 3. Let V and W be linear spaces and T : V → W a linear map. a) Assume the kernel of T is trivial, that is, the only solution of the homogeneous equation T ~x = 0 is ~x = 0. Prove that if T (~x) = T (~y ), then ~x = ~y . b) Conversely, if T has the property that “if T (~x) = T (~y ), then ~x = ~y ,” ...
