求 Golang 中复数的反余弦
Go 语言借助 cmplx 包，为复数的基本常数和数学函数提供内置支持。您可以借助数学/cmplx 软件包提供的 Acos()函数找到指定复数的反余弦。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 Acos()函数。
语法:
func Acos(x complex128) complex128
让我们借助给定的例子来讨论这个概念:
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)
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)
