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。您可以在 math/cmplx 包提供的Tan()函数的帮助下找到指定复数的正切。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 Tan()函数。
句法:
func Tan(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 tangent value of the given complex number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
// Finding Tangent of the
// specified complex number
// Using Tan() function
res_1 := cmplx.Tan(2 + 5i)
res_2 := cmplx.Tan(-1 + 8i)
res_3 := cmplx.Tan(-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: (-6.872163880119275e-05+1.000059350149i)
Result 2: (-2.04655908767745e-07+1.0000000936622975i)
Result 3: (-1.5122148957917884e-06-1.0000006920751883i)
示例 2:
// Golang program to illustrate how to find
// the tangent 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 tangent
cvalue_1 := cmplx.Tan(cnumber_1)
cvalue_2 := cmplx.Tan(cnumber_2)
// Sum of two tangent values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println("Complex Number 1: ", cnumber_1)
fmt.Println("Tangent 1: ", cvalue_1)
fmt.Println("Complex Number 2: ", cnumber_2)
fmt.Println("Tangent 2: ", cvalue_2)
fmt.Println("Sum : ", res)
}
输出:
Complex Number 1: (1+2i)
Tangent 1: (0.033812826079896684+1.0147936161466335i)
Complex Number 2: (3+6i)
Tangent 2: (-3.433535799139611e-06+0.9999882010834397i)
Sum : (0.033809392544097545+2.014781817230073i)
