[ISS] Example exercises

[Giuseppe Bianchi < >]

First set of "possible" exercises, here: so far I imagined just 6 
possible "types" of exercises, if I think to other types (i.e. covering 
different parts of the class), I'll share them later on.

Please:

1) COLLABORATE USING THIS LIST to discuss them (rather than asking me), 
so that everybody benefits from your discussion.

2) If someone wishes to write the solutions, you are MOST welcomed 
(actually, you would do a favor to the next year students), and please 
send me back the solutions. (for instance, you might open a gdoc online, 
so that you can work on it and then share the link to anyone else which 
may refine/correct/extend the writing.

3) Numerical solutions: should be correct as I used mathematica, but I 
produced them very fast so no guarantee.

4) Computation: as said, I used mathematica here so some computations 
MIGHT be overly complex if done during the exam. Do NOT worry: in the 
questions I will give next friday I'll make sure that all computations 
are feasible using a small/basic calculator (I mean: the "calcolatrice" 
you used for your maturity exam or similar)

5) last but not least: you're also ENCOURAGED to "invent" and share with 
your colleagues (over this list) exercises along this line, so as to 
increase the training set!
