求 Golang 中复数的双曲正切
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 Tanh()函数找到指定复数的双曲正切值。因此，您需要在 import 关键字的帮助下在程序中添加一个 math/cmplx 包来访问 Tanh()函数。
语法:
func Tanh(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 tangent of the specified complex
// number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
// Finding hyperbolic tangent of
// the specified complex number
// Using Tanh() function
res_1 := cmplx.Tanh(1 + 5i)
res_2 := cmplx.Tanh(-2 + 8i)
res_3 := cmplx.Tanh(-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: (1.2407479829240697-0.1861094776473042i)
Result 2: (-1.0356479469632376-0.010925884335752532i)
Result 3: (-1.16673625724092+0.24345820118572523i)
例 2 :
// Golang program to illustrate how to find the
// hyperbolic tangent 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 tangent
cvalue_1 := cmplx.Tanh(cnumber_1)
cvalue_2 := cmplx.Tanh(cnumber_2)
// Sum of two hyperbolic tangent values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println("Complex Number 1: ", cnumber_1)
fmt.Println("Hyperbolic tangent 1: ", cvalue_1)
fmt.Println("Complex Number 2: ", cnumber_2)
fmt.Println("Hyperbolic tangent 2: ", cvalue_2)
fmt.Println("Sum : ", res)
}
输出:
Complex Number 1: (0+2i)
Hyperbolic tangent 1: (0-2.185039863261519i)
Complex Number 2: (4+6i)
Hyperbolic tangent 2: (0.9994339325466381-0.0003597965782916252i)
Sum : (0.9994339325466381-2.1853996598398107i)
