(d) If u, v and w are vectors, determine whether each one of the following is a vector, scalar or does not exist. Explain. (i) u - 3v (ii) u - 5(v \cdot w) (iii) |u| - 5(v \cdot w) (3) What question(s) do you have trouble with?

Step 1
When we subtract a vector from another vector, the result is also a vector. In this case, u - 3v represents the vector u with 3 times the vector v subtracted from it. Show more…

If u and v are the vectors below, solve the following equation for the vector x. u = [-5, -1, 2] v = [-3, -1, 3] 3v + u + 3x = 2v - (3x - 2u) x = [0, 0, 0]

(a) Find all vectors $ v $ such that $$ \langle 1, 2, 1 \rangle \times v = \langle 3, 1, -5 \rangle $$ (b) Explain why there is no vector $ v $ such that $$ \langle 1, 2, 1 \rangle \times v = \langle 3, 1, 5 \rangle $$
