Statistical Functions

Statistical functions require an argument in order to be used. Using table headers or lists are possibilities. In these cases, "a" is used to represent a list or table header previously defined by the user in the calculator.

    Why isn't their limits(from calculus)?

    Could you implement the two argument arctangent (atan2) function as well? It's a lot more useful than the standard arctangent function, and I'm getting tired of having to redefine it every project.

    Also, because integrals can take a while sometimes, it would be nice to have a way to increase/decrease their accuracy somehow (perhaps just as a graph option) so that we can choose between having a more accurate or a more dynamic graph.

    Thanks.

    Would be great if there were a "Fraction" function (converts answer to reduced fraction if possible)... like the TI-84.  Thanks!

    +1 for adding the atan2 function.

    This illustrates why it's more useful than arctan:

    Can anyone tell me what does the sign function listed under other supported functions do?

    Can anyone tell me what the exp function under other supported functions do?  Thanks.
