So it is what it thought it was a piece of code that prohibbits the machine to finding a solution. So maybe the Texas instruments and Casio graphic calculator might have some better efficient code in it so that it does work. I however do like the maple environment while it can do a lot. But having to work around these "bugs" is a bit cumbersome.
Maybe if Maple gecomes as mainstream as students and technicians buying Texas instruments and Casio calculators there is enough capital to get it right...(????) I dont know, but when i was doing studying back in the day Maple was unattainable for most of us. We could not find our way into buying the "cheap" version, or it was not there. The one guy that did pay the price got the best grades. Finished all his homework way before the deadline. And we were struggling with the graphic calculators... Maybe making it more cheap and selling more copies might bring in more money while it is more attainable. Or making it more accesable by getting more contact between universities and maple, or maybe give a large number of copies bought discount. It should be foolproof so that everybody that starts as a freshman gets a copy of Maple. That should bring in more money, and thus creating better quality of the program. A win, win, win.. situation.. :)

Any way the one solution i thought would be the final solution, was not the final solution after all... Yes its a shame, but it is good that i plotted the graph so i could see the flaw. It missed the 2nd answer. :( I will try the other methods now and see if there is a working one.
Just showing that what looks like the solution that would find everything, may not give all the answers everytime.
