I want to plot 2 points {1,1,1} and {2,2,2} using ListPointPlot3D and Tooltip, labelling each point "a" and "b" respectively. ListPointPlot3D[Tooltip[{{1, 1, 1}, {2, 2, 2}}, {"a", "b"}]] doesn't seem to work (it displays "{a,b}" at both points) Thanks for any help... Hi, try this: Show[{ ListPointPlot3D[Tooltip[{{1, 1, 1}}, "a"]], ListPointPlot3D[Tooltip[{{2, 2, 2}}, "b"]] }] Have fun, Alexei Alexei BOULBITCH, Dr., habil. IEE S.A.

Hi Elena and everyone requesting help, Everyone on SAS-L either requests or provides help, so a subject line like HELP is completely meaningless. And so is a subject like SIMPLE NEWBIE QUESTION; first of all a newbie would not be able to decide the question to be simple (and whether a question or problem is simple or not does not matter at all), secondly questions are mostly posed by newbies (and being a newbie does not help getting a question answered more quickly) and thirdly it concerns questions which are being asked (that is trivial, but which question?). Other examples of nonsense subje...

i need the help in programming of mathematica the ascii text is given here: "solve the heat equationusing explicit difference approximation with the help of programming in mathematica" is a function of space cordinate "x" and time cordinate "t", ie u= u(x,t) with the given boundary conditions u(0, t) =u(1, t)= 0 for "t" lies in the closed interval from 0 to 1 and the initial condition u(x,0)=x, when"x"lies in the closed interval from 0 to 0.5 u(x,0)=1-x when "x"lies in the closed interval from 0.5 to 1 The explicit differ...

Sorry. I just copied from Mathematica and pasted it. I have no idea why it becomes something unreadable. The function is just one: A*(1+G)+a*[(1+G)^t]=T, where A,a,t,T are all positive real numbers, and t is no larger than 1. Thanks.

Dear Murray, Suppose f:R^2->R^2 and f is unit distance preserving then it has been proven that f is an isometry. Infact, it has been proven for f:R^n->R^n. Sorry i mistakenly type f:R^3->R^2. I welcome any ideas for f:R^2->R^3. regards, Nabeel On 8/10/06, Murray Eisenberg <murray@math.umass.edu> wrote: > > Unless I misunderstand what you say, it is not possible that a map R^3 > -> R^2 could be an isometry.

please,help us . we have a seious problem, we are designing a radio controlled car that is guided by the PC, to send the data wireless between the PC and the Car and vice versa. we use 2 transmitter/reciever circuits from 2 seperate radio controlled car each running with a different frequency (27 MHz & 40 MHz)and modify the functionality of each to do the disered work. but on mounting a transmitter(40MHz) and reciever(27MHz) on the car, and attach another transmitter(27MHz) and reciever(40MHz) to the PC; we found that on sending signals from the car to the PC on the transmitter & rec...

I think most people this entire discussion does not have any practical importance. Obviously something like this: 2*Unevaluated[1+1] 2 Unevaluated[1+1] is extremly unlikely to have any practical use. After all, we use Unevaluated when we want something to remain unevaluated, whereas here only two things can happen: either one will be left with Unevaluated[something] or the "something" will evaluate. Both of these outcomes are obsiously undesirable. Why should one ever use anything like this in a program? In fact if for some unimaginable reason somone neede...
