In this assignment you are required to create one or more
(maximum 3) Haskell programs that will contain at least 15
functions (in total, including pattern overloads). Your
program(s) should have a meaningful purpose. You can choose any
topic or calculation you like (provided it is not extremely
simple), but you are not allowed to copy/paste from the internet.
Some ideas include physics based calculation (think physics I/II
topics) and geometry based calculations (not square or rectangle,
do something that is slightly more involved like volume and
perimeter of a cylinder).
You have to submit a single haskell file and a PDF document that
includes your codes as well as explanation of each function. Your
program should compile and run in a standard Haskell environment.
Programs that do not run will be penalized severely.
