The EduCalc Classic app, rewritten from the ground up:

-- All screens have portrait and landscape
-- Polynomial solver up to 10th degree
-- Wide range of settings for font sizes and graph line widths
-- Updates to this version will be more frequent, going forward
-- Matrix calculator more intuitive and is integrated with main calculator screen
-- Table has an "ask" mode where you enter input values and it gives you the outputs.
-- Please report bugs to the email address inside the app


Features:

1) Scientific Calculator. A lot of thought has gone into the design of the keyboard, which gives you everything you need while keeping the keys as large as possible. 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.
• Define and name your own constants
• Summations
• Complex numbers!
• Sig figs (enable under settings)
• Programmable keys (enable under settings)

2) Graphing. Capabilities:
• Graph up to nine equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Can graph in polar coordinates.
• Can graph parametric equations.
• Can graph parametric equations.
• Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps cant do this!

3) Vector and Matrix calculator. Vector dot and cross products. Multiply and add matrices. Determinant, transpose, Eigenvalues and Eigenvectors.

4) 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.

5) Triangle solver. Enter three sides, two sides and an angle, or two angles and a side, and the solver calculates the rest.

6) Polynomial solvers. Find the roots of a polynomial, up to 10th degree.

7) System of linear equations solver.

8) The reference hits the high points of the following subjects:
algebra, calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics. So if you need a reminder of a trig identity . . . or the quadratic formula . . . or the chain rule from calculus . . . and so on, its right there for you.

9) A unit converter. Your data are in meters, and you need an answer in feet? No problem! 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 physics problem sets! You can also define your own units.

10) Constants for scientific calculations -- speed of light, strength of gravity at Earths surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you dont have to key in the value. Again, great for physics problem sets!

11) Statistics mode, including options for scatter plots and for regression lines.

12) Works on both iPhone and iPad.

13) Derivatives! (Answer simplification is limited.)


Id love to learn about your comments or suggestions. You can write me at the email address on the settings screen of the app. Thanks!

Endlich eine App, die den Splitscreen unterstützt! Einfache Handhabung und bisher die nützlichste App um Graphen zu zeichnen. Auf der einen Seite diese App, auf der anderen mit dem Apple Pencil schreiben - Top :)

Doskonała aplikacja

Aplikacja rewelacyjna i godna polecenia.

Absolutely Awesome!

I love this app. It gets regular updates and is just GREAT for school! This is a great replacement for that huge TI 89 calculator we all remember. Seriously, this app is worth the money. Im so glad I bought it instead of a way expensive graphing calculator. Youll love it too.

Brilliant!

I have had the free v.1 for years and now that the new one came out I decided to pay for it. Definitely worth it. I love your work man.

Great!

This is such a great app that I use all the time! I love all the features, even the ones Ill never use ( I dont think Ill ever need to solve a 10th degree Polynomial) There are some functions Id like to see: Id like more information of different planets, more constants and other angle solvers and such

One word. AMAZING!

Whenever I have a friend ask me what calculator in using because I answered a question so fast I recommend them this app. Very intuitive and FAR better than a physical graphing calculator as I have a TI-83 and TI-89. Unless Im taking college exams, Im using this calculator. Buy it if youre on the fence or if you simply want better app than the pre installed junk calculator that apple gives you. You will not regret it.

The best, but could be better

As a scientific/graphing calculator, this is the best. The free version is amazing, and for $1 you can get rid of the ad banner. Why not 5 stars? The unit converter displays its result up side down. The answer is correct, but it is very confusing. For example, 12 inches per foot is displayed as (1ft/in).
