If u and v are the vectors below, find the vector w whose tail is at the point halfway from the tip of v to the tip of u and whose head is at the point halfway from the tip of u to the tip of u-v. u = (-2,-4,-5) v = (-3, 5, -1) answer: (2, -7, -3/2)

To find halfway between u and v, calculate u-v and divide by 2. To find halway from u to u-v, calculate u-(u-v) and divide by 2. Subtract the two points you get and there's your answer!

ok ill try it, thanks!

when you say divide by 2, do you mean multiply each number by 1/2?

u = (-2,-4,-5) v = (-3, 5, -1)I don't know if I'm too late... (u-v) = (1,-9,-4) P=1/2(u-v) = (1/2,-9/2,-2) u-(u-v) = (-3,5,-1) Q=1/2(u-(u-v))=(-3/2,5/2,-1/2) P-Q=(2,-7,-3/2) Make sense?
