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Cot()函数找到指定复数的余切。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 Cot()函数。
句法:
func Cot(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
// cotangent value of the given complex number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
// Finding cotangent of the
// specified complex number
// Using Cot() function
res_1 := cmplx.Cot(2 + 5i)
res_2 := cmplx.Cot(-1 + 8i)
res_3 := cmplx.Cot(-1 - 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: (-6.871348192386196e-05-0.9999406486514081i)
Result 2: (-2.0465587043065668e-07-0.9999999063376698i)
Result 3: (-1.5122128026576863e-06+0.9999993079230043i)
示例 2:
// Golang program to illustrate how to find the
// cotangent value of the given complex number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
cnumber_1 := complex(1, 2)
cnumber_2 := complex(3, 6)
// Finding cotangent
cvalue_1 := cmplx.Cot(cnumber_1)
cvalue_2 := cmplx.Cot(cnumber_2)
// Sum of two cotangent values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println("Complex Number 1: ", cnumber_1)
fmt.Println("Cotangent 1: ", cvalue_1)
fmt.Println("Complex Number 2: ", cnumber_2)
fmt.Println("Cotangent 2: ", cvalue_2)
fmt.Println("Sum : ", res)
}
输出:
Complex Number 1: (1+2i)
Cotangent 1: (0.03279775553375259-0.984329226458191i)
Complex Number 2: (3+6i)
Cotangent 2: (-3.433616824537947e-06-1.0000117990439865i)
Sum : (0.03279432191692805-1.9843410255021774i)
