Question

How to use the cosh() function to get the hyperbolic cosine of a number in Rust

Answer 1

fn main() {
    println!("cosh(-1) = {}", f64::cosh(-1.0));
    println!("cosh(1) = {}", f64::cosh(1.0));
    println!("cosh(0) = {}", f64::cosh(0.0));
    println!("cosh(-0) = {}", f64::cosh(-0.0));
    println!("cosh(0.9) = {}", f64::cosh(0.9));
    println!("cosh(PI) = {}", f64::cosh(std::f64::consts::PI));
    println!("cosh(PI * 2) = {}", f64::cosh(std::f64::consts::PI * 2.0));
    println!("cosh(PI / 2) = {}", f64::cosh(std::f64::consts::PI / 2.0));
    println!("cosh(PI / 3) = {}", f64::cosh(std::f64::consts::PI / 3.0));
}
