1- Is there any guide where I can learn post script notation for
mathematical expressions well? i.e *x^3* is written as *x 3 exp* in
postscript notation.

2- When you want to skech a function of two variables, do you really need to
 and what happenes if you do not put it? will you get the wrong graph?

3- How do you know which valuve of Alpha and Beta you need to use?

I attach my current assignment  solution here as a pdf file and I sketched
the two functions of two variables by without calling Alpha and Beta.

Can you please look at the graphs in my file and say I am on the right track
or not?
