Another Quick Vector Question
1. The problem statement, all variables and given/known data
Find the vector with the components: Ax=3.2 Ay= -5.15
3. The attempt at a solution
-5.15^2 + 3.2^2= 36.76
sq root of 36.76= 6.06
So, the magnitude is 6.06. Now for the direction....
So, the direction is 58.7
Am I right? Thanks so much!

other than that, everything else seems good.
try using tan theta = y/x .. it's easier to use

So does that mean...
ArcTan(-1.6)= -57.99 degrees
How can I have a negative angle?
