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 uv.
u = (2,4,5)
v = (3, 5, 1)
answer: (2, 7, 3/2)

Best ResponseYou've already chosen the best response.1To find halfway between u and v, calculate uv and divide by 2. To find halway from u to uv, calculate u(uv) and divide by 2. Subtract the two points you get and there's your answer!

Best ResponseYou've already chosen the best response.0when you say divide by 2, do you mean multiply each number by 1/2?

Best ResponseYou've already chosen the best response.1u = (2,4,5) v = (3, 5, 1)I don't know if I'm too late... (uv) = (1,9,4) P=1/2(uv) = (1/2,9/2,2) u(uv) = (3,5,1) Q=1/2(u(uv))=(3/2,5/2,1/2) PQ=(2,7,3/2) Make sense?
