Finding the Sine of Complex Number in Golang

• Last Updated : 02 Apr, 2020

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 sine of the specified complex number with the help of the Sin() 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 Sin() function.

Syntax:

func Sin(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 sine value of the given complex number  package main  import (    "fmt"    "math/cmplx")  // Main functionfunc main() {      // Finding sine of the     // specified complex number    // Using Sin() function    res_1 := cmplx.Sin(2 + 5i)    res_2 := cmplx.Sin(-1 + 8i)    res_3 := cmplx.Sin(-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: (67.47891523845587-30.879431343588244i)
Result 2: (-1254.1949676545178+805.3091464217314i)
Result 3: (-461.3928755590023-296.25646574921427i)

Example 2 :

 // Golang program to illustrate how to find// the sine value of the given complex number  package main  import (    "fmt"    "math/cmplx")  // Main functionfunc main() {      cnumber_1 := complex(1, 2)    cnumber_2 := complex(3, 6)      // Finding sine    cvalue_1 := cmplx.Sin(cnumber_1)    cvalue_2 := cmplx.Sin(cnumber_2)      // Sum of two sine values    res := cvalue_1 + cvalue_2      // Displaying results    fmt.Println("Complex Number 1: ", cnumber_1)    fmt.Println("Sine 1: ", cvalue_1)      fmt.Println("Complex Number 2: ", cnumber_2)    fmt.Println("Sine 2: ", cvalue_2)    fmt.Println("Sum : ", res)  }

Output:

Complex Number 1:  (1+2i)
Sine 1:  (3.165778513216168+1.9596010414216063i)
Complex Number 2:  (3+6i)
Sine 2:  (28.466112195402218-199.69451226216125i)
Sum :  (31.631890708618386-197.73491122073966i)
