### 4.2.2. Points and Vectors

Points and vectors may be entered in Cartesian or polar coordinates (see Numbers and Angles).

Note: Upper case labels denote points whereas lower case labels refer to vectors.

Examples:

· To enter a point P or a vector v in Cartesian coordinates use P = (1, 0) or v = (0, 5).

· In order to use polar coordinates type in P = (1; 0°) or v = (5; 90°).
