Python math.radians() method is an efficient way of converting an angle from degrees to radians. Note that 1 degree = π/180 radians.
Syntax of Python math.radians() Method
math.radians(deg)
Parameters
deg - Any angle in degrees that must be converted into radians.
Return
This method returns a floating point value representing an angle in radians.
Example 1: Use the math.radians() Method in Python
import math
x = 70
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
x = -109
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
x = math.pi
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
x = math.inf
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
x = 0
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
Output:
The conversion of 70 degrees into radians is 1.2217304763960306.
The conversion of -109 degrees into radians is -1.9024088846738192.
The conversion of 3.141592653589793 degrees into radians is 0.05483113556160755.
The conversion of inf degrees into radians is inf.
The conversion of 0 degrees into radians is 0.0.
Note that the values may either be positive or negative. These methods are used in mathematical computations related to geometry and have a certain application in astronomical computations.
Example 2: TypeError When Using math.radians() Method
import math
# entering a string
x = "Hi"
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
# entering a list
x = [1, 2, 3]
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
# entering complex numbers
x = 1 + 5j
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
Output:
Traceback (most recent call last):
File "main.py", line 7, in <module>
value=math.radians(x)
TypeError: must be real number, not str
Traceback (most recent call last):
File "main.py", line 15, in <module>
value=math.radians(x)
TypeError: must be real number, not list
Traceback (most recent call last):
File "main.py", line 22, in <module>
value=math.radians(x)
TypeError: can't convert complex to float
The above code snippets show all possible syntactic errors that might occur when using the math.radians() method.
Example 3: The math.radians() Method and Its Inverse
import math
x = 70
value = math.radians(x)
print(f"The conversion of {x} degrees into radians is {value}.")
deg = math.degrees(value)
print(f"The conversion of {value} radians into degrees is {deg}.")
Output:
The conversion of 70 degrees into radians is 1.2217304763960306.
The conversion of 1.2217304763960306 radians into degrees is 70.0.
The angle can be either an integer or floating point value.
