cmath is Python built-in module that is used for complex number mathematics. cmath module has a method tan() that returns tangent of the complex number passed to it.
Syntax: cmath.tan(Z)
Parameter: It requires only one parameter i.e the number for which tangent needs to be calculated.
Return: Returns a complex number that is the tangent of the number passed.
Example 1:
Python3
# Import the Library import cmath # Printing the result print (cmath.tan(5 + 3j)) |
Output:
(-0.002708235836224072+1.0041647106948153j)
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.tan(1)) |
Output:
(1.5574077246549023+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.tan()) |
Output:
TypeError: tan() takes exactly one argument (0 given)
