Struct Hyperbola2d 

pub struct Hyperbola2d { /* private fields */ }

One branch of a hyperbola in the plane, c + a cosh t x + b sinh t y, parameterized by t over a finite domain.

Implementations

impl Hyperbola2d

pub fn over(hyperbola: Hyperbola2, start: f64, end: f64) -> OgeomResult<Self>

A hyperbola branch over [start, end] in its natural parameter.

Errors

OgeomError::Construction if the interval is not finite and increasing.

pub const fn hyperbola(&self) -> Hyperbola2

The underlying hyperbola.

pub const fn is_reversed(&self) -> bool

Whether the curve runs its domain backwards.
