Implementations

impl Trig2

pub fn value(&self, t: f64) -> f64

Value at t.

pub fn derivative(&self, t: f64) -> f64

First derivative at t.

pub fn second(&self, t: f64) -> f64

Second derivative at t.

pub fn is_finite(&self) -> bool

Whether every coefficient is finite.

Trait Implementations

impl Clone for Trig2

fn clone(&self) -> Trig2

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Trig2

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

Formats the value using the given formatter.

impl Default for Trig2

fn default() -> Trig2

Returns the “default value” for a type.

impl PartialEq for Trig2

fn eq(&self, other: &Trig2) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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