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.
