Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You are allowed to find the hyperbolic cosine of the specified number with the help of the Cosh() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Cosh() function.
Syntax:
func Cosh(y float64) float64
- If you pass +Inf or -Inf in this function, then this function will return +Inf.
- If you pass NaN in this function, then this function will return NaN.
- If you pass 0 in this function, then this function will return 1.
Example 1:
// Golang program to illustrate how to find // the hyperbolic cosine of the given number package main import ( "fmt"
"math"
) // Main function func main() { // Finding the hyperbolic
// Cosine of the given value
// Using Cosh() function
res_1 := math.Cosh(math.Pi / 4)
res_2 := math.Cosh(math.Inf(-3))
res_3 := math.Cosh(0)
res_4 := math.Cosh(math.NaN())
res_5 := math.Cosh(math.Pi)
// Displaying the result
fmt.Printf( "Result 1: %.1f" , res_1)
fmt.Printf( "\nResult 2: %.1f" , res_2)
fmt.Printf( "\nResult 3: %.1f" , res_3)
fmt.Printf( "\nResult 4: %.1f" , res_4)
fmt.Printf( "\nResult 5: %.1f" , res_5)
} |
Output:
Result 1: 1.3 Result 2: +Inf Result 3: 1.0 Result 4: NaN Result 5: 11.6
Example 2:
// Golang program to illustrate how to find // the hyperbolic cosine of the given number package main import ( "fmt"
"math"
) // Main function func main() { // Finding hyperbolic cosine
// of the given number
nvalue_1 := math.Cosh(math.Pi / 3)
nvalue_2 := math.Cosh(math.Pi / 6)
// Sum of the given values
res := nvalue_1 + nvalue_2
// Displaying results
fmt.Printf( "%.1f + %.1f = %.1f" ,
nvalue_1, nvalue_2, res)
} |
Output:
1.6 + 1.1 = 2.7
