Python – cmath.sin() function

cmath is Python built-in module that is used for complex number mathematics. cmath module has a method sin() that returns sine of the complex number passed to it.

Syntax: cmath.sin(Z)

Parameter: It requires only one parameter i.e the number for which sine needs to be calculated.

Return: Returns a complex number that is the sine of the number passed.

Example 1: 



Python3

filter_none

brightness_4
code

# Import the Library
import cmath 
  
# Printing the result
print (cmath.sin(5 + 3j))

chevron_right






                        filter_none










Output:


(-9.654125476854839+2.841692295606352j)



Example 2: In this example real number is passed but the returned result is still a complex number.

                                    play_arrow




                                    link

                                    brightness_4

                                    code
                                




















# Import the Library 


import cmath  


  


# Printing the result 


print (cmath.sin(1))



















                        chevron_right







                        filter_none










Output:


(0.8414709848078965+0j)



Example 3: In this example no argument is passed in this case TypeError will be thrown

                                    brightness_4

                                    code
                                




















# Import the Library 


import cmath  


  


# Printing the result 


print (cmath.sin())



















                        chevron_right







                        filter_none










Output:


TypeError: sin() takes exactly one argument (0 given)
