basis Given a matrix, returns the basis of the linear subspace defined by the set of vectors in the matrix.

basis(Matrix))

Example:

basis([[1,2,3],[4,5,6],[7,8,9],[10,11,12]]) gives [[-3,0,3],[0,-3,-6]]

black Used in the Symbolic view of the Geometry app. In the definition of a geometric object, including the statement “display=black” specifies that the object defined will be drawn in black.

blue Used in the Symbolic view of the Geometry app. In the definition of a geometric object, including the statement “display=blue” specifies that the object defined will be drawn in dark blue.

bounded_function Returns the argument returned by a limit function thereby indicating that the function is bounded.

breakpoint Used in programming to insert an intentional stopping or pausing point.

canonical_form Returns a second degree trinomial in canonical form.

canonical_form(QuadraticExpr,[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(Object1, Object2,…)

Example:

cat("aaa",c,12*3) gives "aaac36"

cFactor Returns an expression factorized over the complex field (on Gaussian integers if there are more than two ).

cfactor(Expr)

Example:

cFactor(x^2*y+y) gives (x+i)*(x-i)*y
