# Thread: Vectors u, v and w

1. ## Vectors u, v and w

Use vetors u, v and w to find each expression.

u = 2i - 3j + k

v = -3i + 3j + 2k

w = i + j + 3k

(1) v x w

(2) v x (4w)

2. What are you exactly having troubles with? This is again another plug-n-chug question. Show your work and we'll see if there are any errors.
