Question

IF A PAIR IS IN THE SAME QUADTRENT DO I SUBTRACT OR ADD

Answer 1

I’m not sure which “pair” or operation you mean — can you clarify? Common meanings and quick rules:

1) Ordered pairs (points) — finding the difference/displacement:
- Always subtract coordinates: Δx = x2 − x1, Δy = y2 − y1.
- If you just want the distance along an axis, take the absolute value of the difference (|x2 − x1|, |y2 − y1|).
Example: between (3,4) and (7,9): Δx = 7−3 = 4, Δy = 9−4 = 5.

2) Reference angle in trig (if you mean an angle in a quadrant):
- QI: reference = θ
- QII: reference = 180° − θ
- QIII: reference = θ − 180°
- QIV: reference = 360° − θ
(Use π instead of 180° for radians.)

3) Adding/subtracting vectors or components:
- To add vectors, add corresponding components.
- To subtract vectors, subtract components.

If you tell me which situation you mean (points, trig reference angles, vectors, etc.) I’ll give a specific example.
