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
# Import the Library import cmath # Printing the result print (cmath.sin( 5 + 3j )) |
Output:
(-9.654125476854839+2.841692295606352j)
Example 2: In this example real number is passed but the returned result is still a complex number.
Python3
# Import the Library import cmath # Printing the result print (cmath.sin( 1 )) |
Output:
(0.8414709848078965+0j)
Example 3: In this example no argument is passed in this case TypeError will be thrown
Python3
# Import the Library import cmath # Printing the result print (cmath.sin()) |
Output:
TypeError: sin() takes exactly one argument (0 given)
