Homework Statement
Suppose vector C = vector A + vector B where vector A has components vector A x = 4, vector A y = 2 and vector B has components vector B x = -3, vector B y = -5.
(a) What are the x- and y- components of vector C ?
I've solved this to figure out that x = 1 and y = -3 for C
(b)What are the magnitude and direction of vector C ?
magnitude I've solved this to be 3.2
direction ? (clockwise from the x-axis) This is what I can't get. I've solved for the angle and gotten -72 degrees using tan -3/1. Does anybody know what I'm doing wrong?
