That 3rd one is a savage bra!!!
I like the wormhole!
Most of my mathcad stuff is for calculations. I used to use it when I was at uni and for a few years afterwards. I got a copy of mathcad a year or two ago, but really haven't used it much - just played around. These days I find I've gotten so used to working out ways of solving problems in Excel, say, that I don't have much use anymore for the heavy maths and mathcad. I used to do lots of vector, matrix and eigenvectors, calculus and differential equation type stuff in the early years of my career. I don't do that stuff any more.
Its a bit sad really because it used to seem so easy, but now I'm so out of touch with REAL mathematics...
What I really need is the time to sit down and work on project with it... I have thought about doing a plot of gravitational field strength for a 2 body orbiting system - obviously to show the Lagrangian points, but I haven't had the time to really get anywhere with it.
Do you play with the animation capability at all? I don't think Mathcad had animations back in the early days (Mathcad 1 and maybe mathcad 3
I think I used). I have Mathcad 13 now... I have no idea how much it's capable of, but I would only be capable of using a fraction of a percent of what it could do!
