I'm currently doing a packet for a final I have soon, there are a few questions that I'm not too sure of the answer for...

1. Find the components of a vector with the given initial and terminal points. Write an equivalent vector in terms of it's components.

P1 (4,-2); P2 (-3,-3)

2. Find the horizontal and vertical components of each vector. Write an equivalent vector in the form "v = a1i + a2i"

Magnitude = 4, Direction angle = 15PI/8
