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Acos()函数找到指定复数的反余弦值。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 Acos()函数。

句法:

func Acos(x 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 inverse cosine of
// complex number
package main
  
import (
    "fmt"
    "math/cmplx"
)
  
// Main function
func main() {
  
    // Finding inverse cosine of the
    // specified complex number
    // Using Acos() function
    res_1 := cmplx.Acos(3 + 5i)
    res_2 := cmplx.Acos(-4 + 8i)
    res_3 := cmplx.Acos(-8 - 7i)
  
    // 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: (1.0367972572007265-2.4598315216234306i)
Result 2: (2.031957962047241-2.886039504947561i)
Result 3: (2.4205679446613617+3.0565545070216835i)

示例 2:

// Golang program to illustrate how to find
// Inverse Cosine of Complex Number
package main
  
import (
    "fmt"
    "math/cmplx"
)
  
// Main function
func main() {
  
    cnumber_1 := complex(5, 7)
    cnumber_2 := complex(6, 9)
  
    // Finding inverse cosine
    cvalue_1 := cmplx.Acos(cnumber_1)
    cvalue_2 := cmplx.Acos(cnumber_2)
  
    // Sum of two inverse cosine values
    res := cvalue_1 + cvalue_2
  
    // Displaying results
    fmt.Println("Complex Number 1: ", cnumber_1)
    fmt.Println("Inverse Cosine 1: ", cvalue_1)
  
    fmt.Println("Complex Number 2: ", cnumber_2)
    fmt.Println("Inverse Cosine 2: ", cvalue_2)
    fmt.Println("Final sum: ", res)
  
}

输出:

Complex Number 1:  (5+7i)
Inverse Cosine 1:  (0.9537320301189085-2.846288828208389i)
Complex Number 2:  (6+9i)
Inverse Cosine 2:  (0.9847612348751953-3.075060767946888i)
Final sum:  (1.9384932649941038-5.921349596155277i)
