Let W be the union of the and quadrants in the xy-plane. That is, let . Complete parts a and b below. a. If u is in W and c is any scalar, is cu in W? Why? A. If u is in W, then the vector cuc is in W because c0 since . B. If u is in W, then the vector cuc is not in W because c0 in some cases. C. If u is in W, then the vector cuc is in W because since . Your answer is correct. b. Find specific vectors u and v in W such that uv is not in W. This is enough to show that W is not a vector space. Two vectors in W, u and v, for which uv is not in W are nothing. (Use a comma to separate answers as needed.)
