-Get support online at RKalk.com, or email us directly: [email protected]
The RK-83 grapher is intuitive, powerful, and easy to use. The features youll love:
-Touchable panning and pinch zooming
-Vibrant multi-colored graphs
-The best graph tracing youve ever seen
-Full screen shots
Version 1.2 is available now! It adds the much requested degree/radian mode! Its faster and more powerful than ever!
New in Version 1.2:
-Create and modify lists: sortA(seq(rand,X,1,10))
-User-defined functions: func(X, X^2)->G
-While loops: while(not(isPrime(X)), X+1->X)
-Degree and radian angle modes (in Settings below the Graph button)
-Quickly adjust your graph scale for "Degree Mode" with the new "ZoomTrig" button
-Faster graphing

good caculator
Pas mal
Les graphes sont corrects. Mais la précision est très moyenne : sin(pi)=-4.10206857e-10 ?! cos(pi/2)=-2.051034285e-10 ?! e^(i*pi)+1=-4.10207e -10i ?! A peu près 90% de la TI-83 est implémenté. Des choses ridicules comme le pi du Kansas. Mais finalement, cest très correct pour le prix.
Bien mais plante
Sympa mais des quon souhaite utiliser une fonction math, lappli plante sur iPhone 4s iOS 5.0.1.... Donc inutilisable. Dommage car le design est tres réussi.
Génial jusquà dernière mise à jour
Nest pas supportée par iOS 10 Dommage
Absturz bei Grafikmodus
Auf der Suche nach dem besten Rechner für das iPhone hab ich auch den RK-83 probiert. Leider stürzt das Programm ab, wenn man in den Graph-Modus wechseln möchte! Bitte dringend nachbessern!!
Eingeschränkt genial
Eigentlich ein guter Rechner, ABER das letzte Ergebnis kann nicht in den nächsten Schritt übernommen werden (ANS-Funktion). Das schränkt die Möglichkeiten leider extrem ein. Bitte bitte bald nachbessern!
Perfect!
My math Tudor told me I needed to buy a Texas instruments ti-83 so I could do my graphing calculations. That costs $120.00 so I decided I would check the app store and see if anything was out there that would work. I found this and saw the pricetag was $.99 so I was a bit skeptical but this app definitely proved itself to me. It saved me well over $100 and it does everything the ti-83 would do, my math teacher could hardly believe it.
