Dear Mr. Postma,
Thank you for your answer.
well i have tried to use you program but unfortunately it is not going completely.
the statistics fit is not working properly. actually it isn't getting defined as a fit. i wounder if a code should be inserted at the beginning so the packege will activated?
Also an error statement is showing up at the p2 implementstion. the statement is " Error, (in simpl/min) arguments must be of type algebraic"
As a matter of fact i would like to ask your personal experiance of learning Maple. since 10 days when i have started learning about the program i depend mainly on program help tool as well as a book named "Maple learning guide" by B. Char. so is there other better way to learn this program.
Thank you very much. i appreciate your help.
