(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Sketch the vector difference D = A - B

I have found F = A + B.

2. Relevant equations

A(x) = AcosTHETA

A(y) = AsinTHETA

B(x) = BcosTHETA

A(y) = BsinTHETA

R = sqrt(rx^2 + ry^2)

3. The attempt at a solution

As opposed to the F = A + B I have tried changing the signs of B or multiplying B(x) = -BcosTHETA etcetera and I can't come with the right solution. Do I need to put the angle 37 degrees in the second quadrant? I am confused as how to find -B as A is going to be the same as the first equation (F = A + B).
