take the tangent of a number in go

To take the tangent of a number in Go, you can use the math.Tan() function from the math package.

Here's an example code snippet:

main.go
package main

import (
	"fmt"
	"math"
)

func main() {
	num := 45.0 // angle in degrees
	rad := num * (math.Pi / 180) // convert degrees to radians
	tan := math.Tan(rad)
	fmt.Println(tan)
}

In this example, we first declare a variable num which represents the angle in degrees that we want to find the tangent of. We then convert this angle to radians by multiplying it with π/180.

We then use the math.Tan() function to find the tangent of the angle in radians. Finally, we print the result using fmt.Println().
