First TY Scott
Ok so I am a Calculus Student who has found I can replicate many problems from my text in MAPLE. I am a visual geometric learner, whcih is a reason I LOVE my MAPLE software. Translation I like to see what problems do graphically and numerically. Often professors inform me that you cant have a visual picture for every problem, but if I have a general immage in my head of what the problem does in theory then it helps me to know where the problem is going. Example we all know x^2 and all the shifts reflecctions and stretching and compressing that can occur -f(x), f(-x), f(x+c), f(x-c), f(x)+c, etc. I may be getting a bit to wordy here so On to the questions and better examples.
In my text book (Single Variable Calculus 5e, James Stewart) in appendix A we are working with Sets, elements of sets, unions, intersection, etc.
OUT OF BOOK pg A3
For instance, the set A consisting of all positive integers less than 7 can be written as
A={1,2,3,4,5,6}
We could also write A in set-builder notation as
A={x|x is an integer and 0

"(a,b)={x|a

Did I not explain the questions well enough or does no one know? Also after another about 2 hours I found the answer to question Three so if you have a comment on it I know there is probably more then one way to do it but here is what I found on it.
plot(5-x^2, x = 1 .. 2, filled = true);
So could someone at lleast post a I dont know so I know that people at least care that college students are interested in MAPLE and Continuing the knowledge base.
