Implicit Equation GrapherContinuing on with my current "equations and functions" obsession, I have made an Implicit Equation Grapher "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20091003 22:46:56
Re: Implicit Equation GrapherFun toy! My favourite one that I've found so far is sin(5x) = cos(5x). Why did the vector cross the road? It wanted to be normal. #3 20091003 23:01:45#4 20091003 23:21:11
Re: Implicit Equation GrapherHi MathsisFun; Last edited by bobbym (20091003 23:21:35) 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. #5 20091004 00:51:10
Re: Implicit Equation GrapherThis is really great! Linux FTW #6 20091004 01:04:27
Re: Implicit Equation GrapherHaha, bobbym's is crazy. Why did the vector cross the road? It wanted to be normal. #7 20091004 04:40:17
Re: Implicit Equation GrapherTry this. Code:y=abs(x)*tan(3*sqrt(x^2+y^2)) It’s actually an Archimedean spiral superimposed on its reflection in the yaxis (recall that an Archimedean spiral has the form r = aθ in polar coordinates). To fit more turns into the picture, try y=abs(x)*tan(4*sqrt(x^2+y^2)), y=abs(x)*tan(5*sqrt(x^2+y^2)), etc. #8 20091004 11:47:33

Re: Implicit Equation GrapherThanks bobby, "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #14 20091005 20:51:29
Re: Implicit Equation GrapherI have given it ZOOM capabilities. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #15 20091006 09:35:30

Re: Implicit Equation GrapherOne thing I'd like to see is recognizing that xy is the same thing as x*y. Linux FTW #17 20091006 11:34:09
Re: Implicit Equation Grapher
That is a good idea, possibly hard, but I will look into it. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #18 20091006 21:53:51
