Go 语言在 cmplx 包的帮助下为复数的基本常量和数学函数提供了内置支持。您可以借助 math/cmplx 包提供的Cosh()函数找到指定复数的双曲余弦。因此,您需要借助 import 关键字在程序中添加一个 math/cmplx 包来访问 Cosh()函数。

句法:

func Cosh(y complex128) complex128

让我们在给定示例的帮助下讨论这个概念:

示例 1:

// Golang program to illustrate how to find the
// hyperbolic cosine of the specified complex
// number
package main
  
import (
    "fmt"
    "math/cmplx"
)
  
// Main function
func main() {
  
    // Finding hyperbolic cosine of 
    // the specified complex number
    // Using Cosh() function
    res_1 := cmplx.Cosh(1 + 5i)
    res_2 := cmplx.Cosh(-2 + 8i)
    res_3 := cmplx.Cosh(-1 - 2i)
  
    // Displaying the result
    fmt.Println("Result 1:", res_1)
    fmt.Println("Result 2:", res_2)
    fmt.Println("Result 3:", res_3)
}

输出:

Result 1: (0.43771362521767465-1.1269289521981367i)
Result 2: (-0.5473996002472885-3.5882642538552894i)
Result 3: (-0.64214812471552+1.068607421382778i)

示例 2:

// Golang program to illustrate how to find the
// hyperbolic cosine of the specified complex
// number
package main
  
import (
    "fmt"
    "math/cmplx"
)
  
// Main function
func main() {
  
    cnumber_1 := complex(0, 2)
    cnumber_2 := complex(4, 6)
  
    // Finding hyperbolic cosine
    cvalue_1 := cmplx.Cosh(cnumber_1)
    cvalue_2 := cmplx.Cosh(cnumber_2)
  
    // Sum of two hyperbolic cosine values
    res := cvalue_1 + cvalue_2
  
    // Displaying results
    fmt.Println("Complex Number 1: ", cnumber_1)
    fmt.Println("Hyperbolic cosine 1: ", cvalue_1)
  
    fmt.Println("Complex Number 2: ", cnumber_2)
    fmt.Println("Hyperbolic cosine 2: ", cvalue_2)
    fmt.Println("Sum : ", res)
  
}

输出:

Complex Number 1:  (0+2i)
Hyperbolic cosine 1:  (-0.4161468365471424+0i)
Complex Number 2:  (4+6i)
Hyperbolic cosine 2:  (26.220553750072888-7.625225809442885i)
Sum :  (25.804406913525746-7.625225809442885i)
