Finding the Tangent of Complex Number in Golang
Go language provides inbuilt support for basic constants and mathematical functions for complex numbers with the help of the cmplx package. You are allowed to find the tangent of the specified complex number with the help of the Tan() function provided by the math/cmplx package. So, you need to add a math/cmplx package in your program with the help of the import keyword to access the Tan() function.
Syntax:
func Tan(y complex128) complex128
Let us discuss this concept with the help of the given examples:
Example 1:
package main
import (
"fmt"
"math/cmplx"
)
func main() {
res_1 := cmplx.Tan(2 + 5i)
res_2 := cmplx.Tan(-1 + 8i)
res_3 := cmplx.Tan(-1 - 7i)
fmt.Println( "Result 1:" , res_1)
fmt.Println( "Result 2:" , res_2)
fmt.Println( "Result 3:" , res_3)
}
|
Output:
Result 1: (-6.872163880119275e-05+1.000059350149i)
Result 2: (-2.04655908767745e-07+1.0000000936622975i)
Result 3: (-1.5122148957917884e-06-1.0000006920751883i)
Example 2 :
package main
import (
"fmt"
"math/cmplx"
)
func main() {
cnumber_1 := complex(1, 2)
cnumber_2 := complex(3, 6)
cvalue_1 := cmplx.Tan(cnumber_1)
cvalue_2 := cmplx.Tan(cnumber_2)
res := cvalue_1 + cvalue_2
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)
}

Output:
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)
