Exercise 1
Write a Python program that reads a list of float numbers from the keyboard, 
then uses the math.sin() function to calculate the sine value of the numbers, 
and finally displays the results on the screen.
-------------------------------------------------------------------------------------------
Results:

arcs = [0.0, pi/6, pi/4, pi/3, pi/2]
[0.0, 0.5236, 0.7854, 1.0472, 1.5708]

Give me some angles in rads: 0.0 0.5236 0.7854 1.0472 1.5708
[0.0, 0.5236, 0.7854, 1.0472, 1.5708]
[0.0, 0.5, 0.7071, 0.866, 1.0]
