Fields

• quadratic_coefficient - constant that multiplies quadratic term.
• linear_coefficient - constant that multiplies linear term.
• independent_term - constant that is added to varaible.

Fields

quadratic_coefficient: f64

linear_coefficient: f64

independent_term: f64

Trait Implementations

impl Composable1D<FirstDegreePolynomial, SecondDegreePolynomial> for SecondDegreePolynomial

fn compose(
    self,
    other: FirstDegreePolynomial
) -> Result<SecondDegreePolynomial, Error>

Specific implementation

Composing a second degree polynomial with a first degree polynomial gives another second degree polynomial.

impl Debug for SecondDegreePolynomial

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Differentiable1D<FirstDegreePolynomial> for SecondDegreePolynomial

fn differentiate(&self) -> Result<FirstDegreePolynomial, Error>

Specific Implementation

Differentiation of a second degree polynomial results on a first degree polynomial.

impl Function1D for SecondDegreePolynomial

fn evaluate(&self, x: f64) -> f64

Specific Implementation

Simple evaluation of a second degree polynomial.

impl PartialEq<SecondDegreePolynomial> for SecondDegreePolynomial

fn eq(&self, other: &SecondDegreePolynomial) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
