132 Alphabetical Listing
polyCoeffs()
Catalog >
polyDegree()
Catalog >
polyDegree(Poly [,Var]) ⇒ value
Returns the degree of polynomial
expression Poly with respect to variable
Var. If you omit Var, the polyDegree()
function selects a default from the
variables contained in the polynomial Poly.
Poly must be a polynomial expression in
Var. We recommend that you do not omit
Var unless Poly is an expression in a single
variable.
Constant polynomials
The degree can be extracted even though
the coefficients cannot. This is because the
degree canbe extracted without expanding
the polynomial.
polyEval()
Catalog >
polyEval(List1, Expr1) ⇒ expression
polyEval(List1, List2) ⇒ expression
Interprets the first argument as the
coefficient of a descending-degree
polynomial, and returns the polynomial
evaluated for the value of the second
argument.
