Question \#1 In Python, sub-programs are called functions. Each function in a program should do one and only one subtask. Data get passed back and forth between the "main" section of the program and various functions. The main part may pass data to a function, receive new data from a function, or both. Data received from a function could in turn be passed on to another function. You can imagine data flowing along the connecting lines in the structure chart. That's how we "empower these subprograms to work together." Since most of the trigonometric functions require that the angle is expressed in radians. In this assignment, we will create our own functions in order to convert between radians and degrees. It is quite easy to convert from radians to degrees or from degrees to radians. We have that: 2[radians]=360[degrees] This gives: d[degrees]=r[radians](180) and r[radians]=d[degrees](180) Create two functions that convert from radians to degrees (r2d(x)) and from degrees to radians (d2r(x)) respectively. Save your functions into a separate Python file and import the file when you write your main program. Test the functions thoroughly to make sure that they work as expected
