Functions and commands 377
basis Returns the basis of the linear subspace defined by the set of
vectors consisting of vector 1, vector 2,..., and vector n.
basis(Lst(vector1,...,vectorn))
Example:
basis([[1,2,3],[4,5,6],[7,8,9],[10,11,12]])
gives
[[-3,0,3],[0,-3,-6]]
BEGIN Used in programming to begin a set of statements that should
be taken as a single statement.
bisector Draws the bisector of the angle AB-AC.
bisector((Pnt(A) or Cplx),(Pnt(B) or
Cplx),Pnt(C) or Cplx))
Example:
bisector(0,-4i,4)
draws the line given by y=–x
black Used with display to specify the color of the geometrical
object to be displayed.
blue Used with display to specify the color of the geometrical
object to be displayed.
bounded_function Returns the argument returned by a limit function thereby
indicating that the function is bounded.
BREAK Used in programming to interrupt a loop.
breakpoint Used in programming to insert an intentional stopping or
pausing point.
canonical_form Returns a second degree trinomial in canonical form.
canonical_form(Trinom(a*x^2+b*x+c),[Var])
Example:
canonical_form(2*x^2-12*x+1)
gives
2*(x-3)^2-17
cat Evaluates the objects in a sequence, then returns them
concatenated as a string.
cat(SeqObj)
Example:
cat("aaa",c,12*3)
gives
"aaac3"
