- If perpendicular: use the Pythagorean theorem — the resultant magnitude is √(A² + B²) (direction from arctan of components).
- If not perpendicular: use the law of cosines (or resolve into components) — resultant magnitude is √(A² + B² + 2AB cosθ) and direction from component sums.
- If not perpendicular: use the law of cosines (or resolve into components) — resultant magnitude is √(A² + B² + 2AB cosθ) and direction from component sums.
