        haha It actually gave an answer.

        Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels.


        Input interpretation:
        How much wood would a woodchuck chuck if a woodchuck could chuck wood?
        Result:
        A woodchuck would chuck all the wood he could chuck if a woodchuck could chuck wood.
        HAccording to the tongue twister, although the paper "The Ability of Woodchucks to Chuck Cellulose Fibers" by P.A. Paskevich
        and T.B. Shea in Annals of Improbable Research vol. 1, no. 4, pp. 4-9, JulyAugust 1995, concluded that a woodchuck can
        chuck 361.9237001 cubic centimeters of wood per day.L

                How did you key in the y notation in that equation? (y' - (2xlnx)^-1y = 2xy^3)

                  Just typed it in. It was one of my problems.

                      I was referring to the notation after the y (for the the differential equation order). I guess it's just an apostrophe. I'm still a few classes away from differential equations, so that's foreign to me at this point!

                        oh, yes that is just the ' under the " on the key board. y' (y prime) can be written as dy/dx also.

                          Absolutely cool. That will come in VERY handy!

                          Thank you!
