- RandomPolynomial[ <Degree> , <Minimum for Coefficients>, <Maximum for Coefficients> ]
- Returns a randomly generated polynomial in x of degree d, whose (integer) coefficients are in the range from minimum to maximum, both included.
- Examples:
RandomPolynomial[0, 1, 2]yields either 1 or 2.RandomPolynomial[2, 1, 2]yields a random polynomial with a degree of two and only 1 and 2 as coefficients, for example 2x2 + x + 1.
CAS Syntax
The following command is only available in the 
CAS View.
- RandomPolynomial[ <Variable>, <Degree> , <Minimum for Coefficients>, <Maximum for Coefficients> ]
- Returns a randomly generated polynomial in Variable of degree d, whose (integer) coefficients are in the range from minimum to maximum, both included.
- Examples:
RandomPolynomial[a, 0, 1, 2]yields either 1 or 2.RandomPolynomial[a, 2, 1, 2]yields a random polynomial with a degree of two and only 1 and 2 as coefficients, for example 2a2 + a + 1.
Note: In both cases if minimum or maximum are not integers, round(minimum) and round(maximum) are used instead.
