Für den Mathematiker durchaus empfehlenswert. Nach SpaceTime jetzt das zweite CAS-Programm auf dem Iphone. Der Preis ist deutlich geringer, dafür fehlen einige Funktionen wie die graphische Darstellung. Es ist aber überschaubarer und leichter zu bedienen.

Great

This is just what I have been looking for. I am in calc 3 and I always want to check to make sure I'm integrating correctly. Graphs would be a huge plus though.

Good Math App

Works well within it's limits. I tried it out with a number of sums and integrals and other stuff in Gradshteyn and Ryzhik. In some cases it gives cleaner results than GR. No need to fiddle with the output to find a "nice" version ofthe result. Neither this nor Spacetimecan do some tricky infinite sums or definite integrals Mathematica does easily, though results in Mathematica can be clumsy compared to pocketCAS when they overlap. Comparing to Spacetime on similar problems, Spacetime sometimes produces correct but clumsy expressions that can be simplified by inspection. On this class of problems pocketCAS is better. The interface is also easier to understand and use. But no graphs. Recommended.

Geniales Programm

Das Programm ist sehr übersichtlich aufgebaut. Die Benutzung des Programms wird wesentlich dadurch erleichtert, dass jede Funktion (auf Englisch) kurz erklärt wird und, was besonders hilfreich ist, das jeweils zu verwendende Eingabeformat angegeben und durch Beispiele erläutert wird. Entsprechend dem eigenen mathematischen Kenntnistand kann man das Programm verwenden, auch wenn man vorher noch nicht mit einem CAS-Rechner gearbeitet hat. Ich benutze sowohl PocketCAS als auch SpaceTime. Die Programme ergänzen sich. Zum Rechnen generell und insbesondere für die Integral- und Differentialrechnung nehme ich lieber PocketCAS. SpaceTime brauche ich für die grafische Darstellung.

Great CAS!!!

Very polished app, very nice GUI , I like it very good performance, and lots of functions in the catalog, well done Daniel. I like the app, I will perform a deeply testing in the integration and derivatives parts reporting any issues I can find. Also an overall testing to give good feedback to the developers. Plotting features would improve a lot the app, implement them guys for future updates! =)

Echt Klasse!

Das Programm scheint ganz gut zu sein, jedoch fehlt mir die graphische Darstellung, für die ich noch ein Stern hinzu geben würde. Aber das wichtigste für 5 Sterne , Wehr es für mich durch einen update die oberfläche des Programms auf die deutsche Sprache umzustellen und die nedienungshilfe auf Drusch zu haben!!! Es gebe Dan von mir 5 sterne!!!!!Und wen dies euch alles zu viel arbeit ist, so könnt ihr ja auch einfach eine pdf datei erstellen in der eine deutsche bedienungs hilfe beschrieben ist!Danke

Prima CAS

Von den mir bekannten CAS ist PocketCAS für mich das Programm der Wahl.Tatsächlich ist dieses PocketCAS sehr umfänglich und funktioniert wunderbar. Im Gegensatz zu "Spacetime" verhält es sich so, wie man erwartet (z.B. im Umgang des CAS mit Listen und beim Rechnen mit Matrizen). Spacetime scheint mir im Vergleich kleinlich und wenig komfortabel (auch nicht so umfangreich - oder?). Zeichnen muss man zwar mit einem anderen Programm. Aber es ist ja nicht unbedingt ein Nachteil, wenn man sich hierzu einen Spezialisten herunterläd.Vielleicht sind solche Apps auch für den Einsatz im Schulunterricht besser geeignet, als PC-Programme oder riesenhafte und sehr teure Taschenrechner.

Amazing functionality.

PocketCAS Pro offers all of the functionality of the major Computer Algebra System based programs like Maple, with the convenience of being on your Ipod Touch. With an innovative and simple interface, along with extensive tutorials, it is amazingly easy to get "up to speed" with the program. PocketCAS Pro has an amazing list of features, from the functions of a basic and scientific calculator, to extensive calculus and linear algebra libraries, it has it all. Does amazing work with simplifying and solving integrals, derivatives, multidimensional polynomial series, arbitrary polynomial expression solving, trigonometric solutions, and more. It deals with both the basic and the complex with an amazingly easy to master interface and input method. On top of all of this, it also provides conversions between binary, decimal, hexadecimal, and octal, as well as between degrees and radians. The only setback right now for PocketCAS Pro is that it does not yet support graphing, fortunately, this is the first thing that will be updated once people start buying the program. Certainly a must for anyone in any sort of math class from highschool up through upper level college.

An App to learn from

This app clearly defines each function in its huge inventory, and gives examples that you can work out., You can actually learn from this app. I especially like the ease with which I can solve differnetial and difference equations. The organization of functions by topics is really helpful. This is a delightful addition to our ability to do symbolic math problems easily, anywhere we happen to be.

excellent cas. very quick typing system. my only gripe would be that there is no plotting. also, having the magnifying glass when you move the cursor would be nice as well.

I have purchased many of the calculators out there including the famed spacetime. Nothing compares to this calculator for it's ability to symbolicly calculate equations. If you need a powerful CAS, look no further.

If you are looking for a powerful, mobile computer algebra system, stop here at PocketCAS! I was surprised to see how easy it was to use the built in keyboard, as well as how easy it was to find documentation on the functions I wanted to use. PocketCAS was able to quickly evaluate all the functions I threw at it in close to no time at all.
