Python math.atan() method is an efficient way of calculating the arctangent of a number, x, in radians.
Syntax of Python math.atan() Method
math.atan(x)
Parameters
x |
Any positive or negative value in the range -PI/2 and PI/2 radians. |
Return
The return type of the math.atan() method is a float value representing the arctangent of x in radians.
Example Codes: Use the math.atan() Method in Python
import math
x = math.pi / 6
value = math.atan(x)
print(f"The arctangent of {x} is {value}.")
x = math.pi
value = math.atan(x)
print(f"The arctangent of {x} is {value}.")
x = math.pi / (-2)
value = math.atan(x)
print(f"The arctangent of {x} is {value}.")
Output:
The arctangent of 0.5235987755982988 is 0.48234790710102493.
The arctangent of 3.141592653589793 is 1.2626272556789118.
The arctangent of -1.5707963267948966 is -1.0038848218538872.
Note that the parameters should be in radians. The values may be either positive or negative.
Example Codes: Enter Different Parameters in the math.atan() Method
import math
x = "c"
value = math.atan(x)
print(f"The arctangent of {x} is {value}.")
Output:
Traceback (most recent call last):
File "main.py", line 5, in <module>
value=math.atan(x)
TypeError: must be real number, not str
Note that a TypeError exception may occur if the argument value is not a number.
