Evaluate a polynomial. First argument COEFFICIENTS is a sequence whose elements are the coefficients of the polynomial in descending order. Second argument NUMBER is the argument at which the polynomial is evaluated.
Calculate the roots of a monic quadratic function f(x) = x² + p·x + q Arguments P and Q are the coefficients of the polynomial. Value is a list of two numbers.
Calculate the roots of a general quadratic function f(x) = a·x² + b·x + c Arguments A, B, and C are the coefficients of the polynomial. Value is a list of two numbers.
Calculate the roots of a monic cubic function f(x) = x³ + p·x² + q·x + r Arguments P, Q, and R are the coefficients of the polynomial. Value is a list of three numbers. The first element is a real number.
