Vectors and Points |
- Vectors can be enclosed in several kinds of parentheses:
<,> or (,) or [,]
- Errors are generated coordinate-by-coordinate
- Can get messages about wrong number of coordinates
- Can check for numeric vectors or vector formulas:
<5,1,-3>
or<5x,1+x,x^2-3>
- Warning: Students can't enter vector formulas. (Yet!)
e.g.,(1,3) - (2,-3)
is not allowed.
