• Degree angle mode returns (r
• Radian angle mode returns re
complexValue can have any complex form. However, an re
causes an error in Degree angle mode.
You must use the parentheses for an (r

polyEval( , )
⇒
List1 List2
polyEval( , )
Interprets the first argument as the coefficient of a descending-degree
polynomial, and returns the polynomial evaluated for the value of the
second argument.

polyRoots()

⇒
Poly Var
polyRoots( , )
ListOfCoeffs
polyRoots( )
The first syntax,
polyRoots(
polynomial Poly with respect to variable Var. If no real roots exist,
returns an empty list: { }.
Poly must be a polynomial in expanded form in one variable. Do not
use unexpanded forms such as y
The second syntax, polyRoots(ListOfCoeffs), returns a list of real
roots for the coefficients in ListOfCoeffs.
Note: See also cPolyRoots(), page 23.
