Interface PolynomialI

public interface PolynomialI

The PolynomialI interface manages a polynomial.

Example: 4.3x^2 is a polynomial where 4.3 is the coefficient constant and the degree is 2.

Method Summary

double	eval(double x) Returns the result of the polynomial calculated with the given x.
double	getCoefficient(int degree) Return the coefficient constant used in the polynomial for the degree specified.

Method Detail

getCoefficient

double getCoefficient(int degree)

The valid request values are 0 <= degree <= 3.

Parameters:

degree - Coefficient constant degree to return

Returns:

Coefficient constant

Throws:

java.lang.IllegalArgumentException - if the degree greater than 3 or degree less than 0.

eval

double eval(double x)

Returns the result of the polynomial calculated with the given x.

Parameters:

x - The x to plug into the equation.

Returns:

the result of the polynomial computed with x
