In python 3.64 use IDLE to write three simple fuctions that meets all requirements below.

Write at least three simple functions inside of your own design: function 1 should just be a polynomial like we've done in class or some other function that calls other predefined functions (like math.sin etc) and combines them and returns something back to the user. function 2 should include at least one if statement. function 3 should use the implicit None but should act on a list.
