Re: Cool graphs using the sgn(x) function!!!well yeah,but the problems in high school are almost always solvable,at least for regular program of teaching. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #27 20120221 04:56:58
Re: Cool graphs using the sgn(x) function!!!That is true and it is very dangerous. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #28 20120221 04:57:47
Re: Cool graphs using the sgn(x) function!!!i think i know why you think so.for the same reason you fear simplification.

Re: Cool graphs using the sgn(x) function!!!Worse than that. It subtly puts into the students mind that all problems have solutions by the standard methods. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Cool graphs using the sgn(x) function!!!thought so.i know you fear general thought.

Re: Cool graphs using the sgn(x) function!!!What exactly are you trying to do with it? In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!Yes, I read it but I do not understand it. The purpose of the piecewise notation is to represent functions that can not be represented by one equation, so why are you going backwards? In mathematics, you don't understand things.

Re: Cool graphs using the sgn(x) function!!!hi bobbym can be represented with a single formula,so i'm guessing other ones can too.

Re: Cool graphs using the sgn(x) function!!!That is what I do not understand. You used parameters a and b? In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!Okay, look at post #32. The piecewise is not defined for lots of points. In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!I am going to bring it down here: 1 and 1 have no definition for them. You want it like that? In mathematics, you don't understand things.

Re: Cool graphs using the sgn(x) function!!!I am not seeing how to get those line segments into one form. In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!Isn't that a 3D plot? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Cool graphs using the sgn(x) function!!!i don't know how you got 3D.it's the graph of y=sgn(x+1)+sgn(x1).

Re: Cool graphs using the sgn(x) function!!!Over there it is written as y sgn(x+1)+sgn(x1). In mathematics, you don't understand things. You just get used to them.
