Continue practicing Go and remembering the school curriculum “Pythagoras pants are equal on all sides!” Or to paraphrase in a more boring version: the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the cathetuses: c^2 = a^2 + b^2
Our titanic task is this: find the third side of a right triangle. Here’s the code:
package main import ( "fmt" "math" ) func main() { var r float64 = 5 var l float64 = 7 // s^2 = r^2 + l^2 s := math.Sqrt(math.Pow(r, 2) + math.Pow(l, 2)) fmt.Println(s) }
In next post we will check is point exists in the circle?
