Exercise: Geometry
We will create a few utility functions for 3-dimensional geometry, representing
a point as [f64;3]
. It is up to you to determine the function signatures.
// Calculate the magnitude of a vector by summing the squares of its coordinates // and taking the square root. Use the `sqrt()` method to calculate the square // root, like `v.sqrt()`. fn magnitude(...) -> f64 { todo!() } // Normalize a vector by calculating its magnitude and dividing all of its // coordinates by that magnitude. fn normalize(...) { todo!() } // Use the following `main` to test your work. fn main() { println!("Magnitude of a unit vector: {}", magnitude(&[0.0, 1.0, 0.0])); let mut v = [1.0, 2.0, 9.0]; println!("Magnitude of {v:?}: {}", magnitude(&v)); normalize(&mut v); println!("Magnitude of {v:?} after normalization: {}", magnitude(&v)); }
