 Apr29 comment How do I draw a polygon defined by a list of data points? The ordering problem may be solved using ListCurvePathPlot.

I'm voting to close this question as off-topic because it does not seem to be related in any direct way to Mathematica. Apr29 reviewed No Action Needed notebooks not opening in mathematica 10 Apr29 comment translating simple mathematica code into an app Welcome Adrian. Unfortunately, as it currently stands, your question is not a good match for our site, as its connection to Mathematica is weak at best. It pains me that I have to vote to close this as off-topic, but don't take this personally and feel free to post further, more mathematica-related questions. Apr29 comment Find recurrence relation for a sum Anyway, most folks want to go the other way: they have a recursive function and need to have a closed form solution. That can be done with RSolve. Not sure if it is possible to go the other way. Apr29 comment Find recurrence relation for a sum Perhaps I'm mistaken, but I feel you missed the point. In a recurrence equation you relate a given element of a sequence to one or more earlier or later elements of the same sequence. In this case, your second definition then should have EV[t_] as the left-hand side, which would be problematic as you haven't specified a stopping criterion. Apr29 comment Find recurrence relation for a sum EVR is not recursive at all. It refers to EV and not to itself. Apr29 comment Plot a simple curve Assuming you have a Mathematica notebook open and have typed Plot[x^2, {x, 0, 2}] a simple shift+enter (or the enter on your numeric pad) with your cursor still on the line should evaluate the input and should get you the plot. Unless, of course, you haven't started the graphical frontend and are now (accidentally) working using the command line version?

PS If /. is new to you, you might want to read at least the ReplaceAll help page. Apr29 comment Difficulty in getting correct Gaussian curve for diffusion of point source You mean: "a program you know, that has been written in C++, works in a way that it can handle peaks in the way you defined", right? You realize that that has nothing to do with C++ itself, do you? Apr29 comment Difficulty in getting correct Gaussian curve for diffusion of point source I don't think your way of defining a point source is correct. The peak has a finite height but a width of zero, so it basically contains nothing.

Apr29 reviewed Approve Plot curves like equation problems Apr29 comment Why are my 3D plots getting inverted? This happened suddenly, I mean, Mathematica behaved normally earlier? Have you recently updated anything? Or perhaps you should update your graphics drivers? Apr29 reviewed Reviewed Why are my 3D plots getting inverted?
