Complete the proof of Property 4 of the following theorem by supplying the justification for each step. Properties of Additive Identity and Additive Inverse Let v be a vector in R", and let c be a scalar. Then the properties below are true. 1. The additive identity is unique. That is, if v + u = v, then u = 0. 2. The additive inverse of v is unique. That is, if v + u = 0, then u = -v. 3. Ov - 0 4. co - 0 5. If cv - 0, then c- 0 or v = 0. 6. -(-v) = v Use the properties of vector addition and scalar multiplication from the following theorem.
