Help with help!
I really hate to bother the people here if I don't have to, but I am finding that the manual usually can not answer my questions. For example, I have a problem with a function of 3 variables, and in the algebra window it is titled as a "Multivariable Function". When I search the manual for this I get no hits, but a request to create a new page about this topic!
It would seem that "Multivariable Function" is a well-defined term in Geogebra, but not according the manual. I just want to know how to learn how to use this wonderful tool, but am very frustrated in trying to do so!
