Graphing Calculator Viewer at Mac App Store analyse

this is just a demo, pretty much a video demonstration of what the paid app can do. On the other hand, the paid app looks great, I just dont see the point of this "free version"

forse è il mio mac, ma non si avvia!!! per di più non mi è possibile cancellare lapp perchè mi appare il messaggio è aperta!!! che fregatura!!!

L’applicazione di grafica scientifica più potente di sempre; la uso dalla prima versione (che accompagnava tutti i Mac) e non ho mai trovato nulla di più potente e insieme semplice da usare; la preferisco addirittura a Mathematica per rappresentare funzioni complesse, e può essere utilizzata anche da chi sa poco o nulla di grafica di funzioni. Scelta per le classi di Matematica della Scuola Europea (II) di Bruxelles.

I use GC every day to explore the physics of slacklines. Indispensable.

In the past 30 years, Ive been stunned speechless by computers on several occasions. I remember the first Macintosh, the first computer speech, the first time I was able to log into a computer thousands of miles away, and the first time I saw Graphing Calculator. By now, most of these feelings have dulled, but Im still in love with Graphing Calculator. Steve Jobs often talks about software thats so powerful, and yet so effortless, that its magical. When you use Graphing Calculator, you get an almost-physical feeling of HOW MATH WORKS. If you have, say y = (some big long equation including x), and you want to solve for x, pick up x and y and drag them around. WHILE YOU ARE DRAGGING, GC will update the equation, keeping it accurate. Its easier than untangling the wires on your earbuds! Type something like y = sin t x -- GC will draw the graph, and add a slider for t. Yank on the slider, and see the results. Click a play button, and it will slide back and forth. Aha, t is affecting "frequency"! Now you understand. You can, of course, grab a chart and drag it for a different perspective. Zoom in and out. Rotate 3D charts. (Even draw 4- and 5-dimensional charts.) GC keeps animating the entire time. More importantly, you can click on equations and find the interesting values. Math is often hard. Graphing Calculator, because its so powerful and effortless, makes it easy to "just mess around" with equations, and in doing so, you really understand them. GC includes some amazing eye-candy -- a bunch of equations that plot a little PAC MAN head, chomping away. Thats nice, but the thing is, you can tweak the equations, control the values, and therefore understand how the whole thing works, and pretty soon youll be making your own silly eye-candy. No more math phobia. There are other programs for solving hard math problems. They are not only slower to solve equations, they take much more time to learn to use. It reminds me that once, long ago, programmers had to punch their programs onto special cards (better not make any mistakes!), and then take the piles of these cards to a special room. The next day, theyd get a printout, usually showing an error or two. Even simple programming required huge amounts of patience, and very few people even wanted to learn. Then Apple and others used the immense power of faster chips to make computers "effortless" -- and now even people who would rather not learn about FLASH RAM or WI FI can take a picture of a product, and within seconds, find out whether the price in the store really is a bargain. Graphing Calculator is like that, for Math. Nothing short of a revolution. It is a pity that Apple stopped including it with the operating system.

Ive been a big user of GC since the beginning back in OS 7 days, and Ron keeps making it better and better. The viewer allows me to email the complete workspace to someone that doesnt own GC and allows them to view it and even run the various interactive bits included in the workspace. Very cool! (and you should definitely consider getting the full version ... 4.0 adds tables (hooray!) and long variable names (three cheers!) among other useful bits. Ive even found the new numeric integration feature useful ... GC is turning into something beyond just a function visualizer ... its now a first class computing tool!) Cant recommend it high enough. And *get the full version*, you wont regret it. Now for the iPad version, Ron?

I was very excited to get this app because I am a high school student in Pre-Calc, unfortunatly after installing the app, it never opened.
