I have been unable to get Maple Player to perform as I thought it would. Actually I can only get it to work with the default functions. Anytime I type in a function I get the following error message: "There was an error trying to generate the plot." or "There was an error during the differentiation of the input function." or "The input value "x
2
+4x+2" should be an algebraic expression." or "There was an error during the execution of finding the root."
