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 cotangent of the specified complex number with the help of the Cot() 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 Cot() function.
Syntax:
func Cot(y complex128) complex128
Let us discuss this concept with the help of the given examples:
Example 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)
} |
Output:
Result 1: (-6.871348192386196e-05-0.9999406486514081i) Result 2: (-2.0465587043065668e-07-0.9999999063376698i) Result 3: (-1.5122128026576863e-06+0.9999993079230043i)
Example 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)
} |
Output:
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)
