## Python math.radians() method

math.radians() method is a library method of math module, it is used to convert angle value from degree to radians, it accepts a number and returns the angle value in radians.

Note: math.radians() method accepts only numbers, if we provide anything else except the number, it returns error TypeError"TypeError: a float is required".

Syntax of math.radians() method:

```    math.radians(x)
```

Parameter(s): x – is the number in degree to be converted into radians.

Return value: float – it returns a float value that is the angle value in radians.

Example:

```    Input:
x = 10.25

# function call

Output:
0.17889624832941878
```

### Python code to demonstrate example of math.radians() method

```# Python code to demonstrate example of

# importing math module
import math

# number in radians
x = 0

x = 0.25

x = 10.25

x = -0.25
```

Output

```math.radians( 0 ):  0.0
math.radians( 0.25 ):  0.004363323129985824
math.radians( 10.25 ):  0.17889624832941878
math.radians( -0.25 ):  -0.004363323129985824
```

TypeError example

```# Python code to demonstrate example of
# math.radians() method with exception

# importing math module
import math

# number in radians
x = "10"
```

Output

```Traceback (most recent call last):
File "/home/main.py", line 9, in <module>
