1. The problem statement, all variables and given/known data I had a problem on my physic hw, and I keep on getting it wrong, so I was wondering: in a vector, if the x direction is negative, and the y direction is positive, would the angle direction also be negative? What happens if the x direction is positive, and the y direction is negative? A degree can't be negative right? also, 2) what does it means when the angle direction is "from the positive x axis" or "counterclockwise from the positive x axis is positive" 2. Relevant equations 3. The attempt at a solution In my hw, I figured out the magnitude already, which is 81.2, and the x direction is -81.22 and y direction is 1.95, so I found the angle direction by tan-1(1.93/-81.22) and got -1.37, but i just ignore the negative sign, since i assume that a degree cant be negative.
