Vector Operations
| Operation | Method | Example |
|---|---|---|
| Addition | Add components | (3,4) + (1,2) = (4,6) |
| Subtraction | Subtract components | (5,7) - (2,3) = (3,4) |
| Scalar Multiple | Multiply each component | 3(2,1) = (6,3) |
| Magnitude | |a| = √(x² + y²) | |(3,4)| = √(9+16) = 5 |
