## Study Notes

### Vector Addition Rules

- According to the parallelogram law, when adding two or more vectors, the resultant vector is the diagonal of a parallelogram formed by the vectors being added.

### Vector Addition in Cartesian Coordinates

- To add vectors in Cartesian coordinates, add corresponding components (x and y) separately.

### Vector Addition Notation

- In the Wolfram Language, vector addition is indicated by the
`+`

operator.

### Sum of Vectors

- The sum of vectors
**u**= âŒ©u1, u2âŒª and**v**= âŒ©v1, v2âŒª is âŒ©u1 + v1, u2 + v2âŒª. - The sum of vectors
**a**= âŒ©a1, a2, ..., anâŒª and**b**= âŒ©b1, b2, ..., bnâŒª is âŒ©a1 + b1, a2 + b2, ..., an + bnâŒª.
