Question

How to compute the hypotenuse h of the triangle in Go

Answer 1

package main

import (
    "fmt"
    "math"
)

func main() {
    // Legs of the triangle
    a := 7.0
    b := 5.0

    // Method 1: Using math.Sqrt and math.Pow
    h1 := math.Sqrt(math.Pow(a, 2) + math.Pow(b, 2))
    fmt.Printf("The hypotenuse (h) is: %.6f\n", h1)

    // Method 2: Using direct multiplication
    h2 := math.Sqrt(a*a + b*b)
    fmt.Printf("The hypotenuse (h) is: %.6f\n", h2)

    // Method 3: Using math.Hypot (simple and safe)
    h3 := math.Hypot(a, b)
    fmt.Printf("The hypotenuse (h) is: %.6f\n", h3)
}



/*
run:

The hypotenuse (h) is: 8.602325
The hypotenuse (h) is: 8.602325
The hypotenuse (h) is: 8.602325
