## What is EduCalc?

Edu Graphing Calculator is written for students, teachers, and lifelong learners.

-- All screens have portrait and landscape
-- Polynomial solver up to 10th degree
-- Wide range of settings for font sizes and graph line widths
-- Additional matrix/systems of equations material in reference, with more coming
-- Copy/Paste works in many places
-- Updates to this version will be more frequent, going forward
-- Please report bugs to the email address inside the app

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.

10) System of equations solver

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 the email address on the App's settings tab.  Thanks!

### 5/5 — Fantastic App - worth much more than I paid

*2025-02-11, version 10.5*

This is my go to app for any calculations and it does so much more than I understand if you only have one calculator app then this one or the pro is the way to go

### 5/5 — The best calculator

*2023-01-09, version 10.5*

This calculator got me through my university math classes from Pre-Algebra through Calculus 3! I still use it regularly for simple things like calculating my budget. It literally does everything.

My fav feature is that the history displays as you do your math, and you can tap on any number displayed there and it auto copies it so you can paste into your next equation.

### 5/5 — Clean interface, practical: a pleasure to use

*2021-08-05, version 10.5*

There are a lot of calculator apps in the Store. This one actually delivers. 

After downloading a bunch I happened upon this gem. The rest are going into the rubbish heap!

Thank you for this app!

### 5/5 — Most powerful free graphing calculator out there!

*2020-10-23, version 10.5*

One wouldn’t even believe how many features this has for free...

### 5/5 — Great app. Works well.

*2019-06-24, version 10.4*

Everything works well. Easy to type in equations.

### 5/5 — Kel

*2019-06-02, version 10.4*

Awesome. Thanks

### 5/5 — Good

*2018-12-20, version 10.4*

Nice app, keep on going.

### 5/5 — Finally a graphing calculator app made with common sense!

*2018-06-06, version 8.8*

great app! Includes all the basic features you’d want from a graphing calculator for Algebra 2, such as making a table and finding maxima and minima
THANK YOU for being the person to finally make a decent graphing calculator!!!

### 5/5 — Great calculator

*2018-04-05, version 8.8*

I teach high school math. We switched to this calculator from the TI series previously used. It can do most of what the TI-84 can do and better. The only down side is we can’t let students use this on an ACT test. The bad reviews must be from people who don’t know how to use it. I have never had a problem with it. Over 200 students have used it over the past 4 years without a single wrong answer or other issue.

### 5/5 — Good app

*2018-03-30, version 8.8*

All the features I have tried so far have been easy and intuitive to use. Very well done.
