take the secant of a number in go

To take the secant of a number in Go, you can use the math package which provides trigonometric functions including the secant (sec) function. Here's an example code snippet:

main.go
package main

import (
    "fmt"
    "math"
)

func main() {
    x := 1.2
    secant := 1 / math.Cos(x)
    fmt.Printf("sec(%v) = %v\n", x, secant)
}

13 lines

In this example, we import the math package and use the math.Cos function to compute the cosine of x. We then take the reciprocal of the cosine to obtain the secant value of x. Finally, we use fmt.Printf to print the result to the console.

Note that the input to the math.Cos function is in radians, so you may need to convert from degrees if your input is in degrees.
