求 Golang 中复数的双曲余弦
原文:https://www . geeksforgeeks . org/find-the-双曲线余弦复数 in-golang/
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 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。
语法:
func Cosh(y 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
// 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)
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)
