求 Golang 中复数的反正弦
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 Asin()函数找到指定复数的反正弦。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 Asin()函数。
语法:
func Asin(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
// the Inverse Sine of Complex Number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
// Finding inverse sine of the
// specified complex number
// Using Asin() function
res_1 := cmplx.Asin(3 + 5i)
res_2 := cmplx.Asin(-4 + 8i)
res_3 := cmplx.Asin(-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: (0.5339990695941702+2.4598315216234306i)
Result 2: (-0.4611616352523445+2.886039504947561i)
Result 3: (-0.849771617866465-3.0565545070216835i)
例 2:
// Golang program to illustrate how to find
// the Inverse Sine 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 sine
cvalue_1 := cmplx.Asin(cnumber_1)
cvalue_2 := cmplx.Asin(cnumber_2)
// Sum of two inverse sine values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println("Complex Number 1: ", cnumber_1)
fmt.Println("Inverse sine 1: ", cvalue_1)
fmt.Println("Complex Number 2: ", cnumber_2)
fmt.Println("Inverse sine 2: ", cvalue_2)
fmt.Println("Final sum: ", res)
}
输出:
Complex Number 1: (5+7i)
Inverse sine 1: (0.617064296675988+2.846288828208389i)
Complex Number 2: (6+9i)
Inverse sine 2: (0.5860350919197013+3.075060767946888i)
Final sum: (1.2030993885956893+5.921349596155277i)
