Crate trig

  

Complete set of trigonometric and hyperbolic functions in Rust.

Summary

This crate defines the Trig trait defining the complete set of trigonometric and hyperbolic functions. Rust already provides the following functions for f32s and f64s:

• trigonometric functions (radians): sin, cos, tan
• inverse trigonometric functions (radians): asin, acos, atan, atan2
• hyperbolic functions: sinh, cosh, tanh
• inverse hyperbolic functions: asinh, acosh, atanh

In addition to these functions, the Trig trait also defines the reciprocal functions and their inverses for both the trigonometric and hyperbolic functions. The complete set of methods defined on the Trig trait is:

• trigonometric functions (radians): sin, cos, tan, csc, sec, cot
• inverse trigonometric functions (radians): asin, acos, atan, acsc, asec, acot
• trigonometric functions (degrees): sind, cosd, tand, cscd, secd, cotd
• inverse trigonometric functions (degrees): asind, acosd, atand, atan2d, acscd, asecd, acotd
• hyperbolic functions: sinh, cosh, tanh, csch, sech, coth
• inverse hyperbolic functions: asinh, acosh, atanh, acsch, asech, acoth
• unit conversions: deg2rad, rad2deg

Implementations

This crate currently implements the Trig trait for the following types/structs:

• f32
• f64

Example

use trig::Trig;

let x = std::f64::consts::FRAC_PI_2;
let abs_difference = (x.csc() - 1.0).abs();

assert!(abs_difference < 1e-16);
