It seems like a simple exercise, but I have been stuck on it for some hours even after reading the documentation. It has the following [description](https://i.stack.imgur.com/vDk0z.png).

A given template needs to be used a starting point:

```
# import the required library

def calculate_cosine(angle_in_degrees):
    # do not forget to round the result and print it
    ...

```

The input samples are provided by the training website itself. So my attempt went like this:

```
#import the required library
import math

def calculate_cosine(angle_in_degrees):
# do not forget to round the result and print it
    math.cos(angle_in_degrees)
    print(round(angle_in_degrees, 2))

```

What's wrong with this code? The unit of the measure should be in radius?

Really appreciate any help with this!
