Cool graphs using the sgn(x) function!!!hi guys 2)two parallel nonhorizontal rays at heights 1 and 1: y=x+sgn(x) Plot of y=x+sgn(x) this can be generalized to two parallel nonhorizontal rays at heights a and b with the formula: but can also be generalized to two nonparallel nonhorizontal rays at heights a and b with the formula: 3)i have also find a way to plot two parallel lines(horizontal or vertical),but unfortunately wolfram won't plot this function. for two vertical lines there are 3 different formulas depending where we want the lines to be.i will give the formula for when the two lines are on the right of the yaxis: Last edited by anonimnystefy (20120220 01:11:45) 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 #2 20120219 08:59:30

Re: Cool graphs using the sgn(x) function!!!I can not see anything, can you fix the tags? 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. #4 20120219 09:38:07

Re: Cool graphs using the sgn(x) function!!!yes,but i looked for ways to do it with only one function.

Re: Cool graphs using the sgn(x) function!!!I can not see any of those images so I am having trouble understanding what you already did. In mathematics, you don't understand things.

Re: Cool graphs using the sgn(x) function!!!i put in some links instead of pictures.it should be fine now 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 #11 20120220 04:44:38
Re: Cool graphs using the sgn(x) function!!!I am still only getting Alpha' s site and that whirring thing. In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!Yes, I have done that. I can now see it all. In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!That is good but you should have asked me first. In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!I would have suggested Geogebra, it comes with Maxima and with latexing capabilities. In mathematics, you don't understand things.

Re: Cool graphs using the sgn(x) function!!!I do not know what Maxima's capabilities for solving recurrences is offhand. They are solved by two methods, generating functions and the auxiliary polynomial. In mathematics, you don't understand things. You just get used to them.

Re: Cool graphs using the sgn(x) function!!!i know them both.for some of them i like GFs more,but for some too hard i like using the AP.

Re: Cool graphs using the sgn(x) function!!!Generally, like DE's only some of them can be solved for. In mathematics, you don't understand things. You just get used to them.
