Description
A powerful, flexible graphing calculator
Does far more than most calculators out there.
Features:
1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:
• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.
2) Graphing. Capabilities:
• Graph up to four equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Graph in polar coordinates.
• Graph parametric equations
• Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this!
3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!
4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework!
5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6) Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition.
7) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.
8) Keep track of significant figures [AKA sig figs]
9) Statistics -- enter data and make a histogram, box and whisker plot, or scatter plot with optional regression line.
If you are viewing this in iTunes, you will see five iPhone screenshots and five iPad screenshots. But even ten shots don't come close to showing everything this calculator can do.
I'd love to hear your comments or suggestions. You can write me at [email protected] -- but without the xyz. Thanks!

Q
How can i see the system of equation that i inserted??
This is the best app for calculating!!
Thanks for making this app
extremely useful app
real good app!!! But, references in the menu at bottom do not pop up.... please show up references!!!!
A Must Have app. For Math~~
I and my son love this app.
어떤 계산기 어플보다 최고네요. Good!!!!!!!
Verry good!
Handy, useful
간단히 쓰기에 좋음. 기본 기능에 충실하였고, 매우 잘 작동함. 내가 제일 자주 사용하는 계산/그래프 어플임
무한 줌인 줌아웃
줌인 줌아웃할때 너무 광범위하게 하면 렉걸리네여.....그 이후론 그래프가 표시도 안되고...그것만 제외하면 그래프앱으로는 좋은거같습니다.
정말 마음에 드는 App이에요^^
올해 대학에 입학했는데요 수학공부할 때 이런 앱이 필요하다 생각했는데요 정말 공짜이면서 많은 걸 할 수 있어서 정말 마음에 들어요^^ 1~3차 방정식의 근을 푸는 기능도 있고 웬만한 양함수는 그래프로 나타낼수있어서 좋구요 그래프간의 교점도 찾아내서 무료인데도 참 좋은거 같습니다^^ 좀 아쉬운건 매개변수 방정식이나 극좌표계, 공간좌표, 음함수는 입력이 안되더군요...(무료엡에 너무 바라는게 많았나..??ㅡㅡㅋㅋㅋㅋㅋ) 유료버젼은 될디 모르지만 아 그리고 입력할 수 있는 그래프가 5개여서 좀 아쉬웠어요..(좀 더..ㅠㅠ) 여하튼 그런거 빼면 정말 추천하고 싶은 앱입니다!!!^^
brilliant!!!
it is perfect to me. there is everything i need.
