Description

Plot functions and trace their graphs with ease! This is a simple graphing calculator with graphing capabilities similar to TI-83 or TI-89 calculators. To start adding equations, tap the graph! There are no ads, because I hate ads.

Features:

* Graph tracer via trackball, trackpad, d-pad(hard or soft)

** Press for current trace position

** Up/down to change functions

* Find intersection of 2 graphs

* Save graph to SD card in "My Graphs"

* Pinch-to-zoom and panning

* Full screen graphing calculator

* Custom equation keyboard

* All colors are customizable

* Long press to bring up soft d-pad (top or bottom)

* Install on external media

I would love to hear suggestions for any improvements or if you have problems using this program. Please email me if you think something is missing or if you would like to request functionality.

I am not able to respond to comments, so please send an email so I can be clear on your request.

Saksham Chawla

Great, but misses one important feature In the app, we can only enter the value of f(x), which creates a problem while entering an equation of a circle, ellipse, hyperbola, etc those in which f(x) is a square value ( y^2 + x^2 = 1). The sqrt function doesn't properly solve the problem. Only the positive part of the figure is seen. Otherwise, a great application

Duc Nguyen

Nice app! Type in f(x)=2cos(100*pi*x) Out to the graph, zoom in and out to see the magic!

desmond lau

Important function missing!! Now I couldn't reset the window! I've input an equation and I zoomed in to get a better view. When I try to reset the window I don't find that option any where. Please fix that.

Marissa Amador

Love it Best graphing app on here! I would like to be able to see graphs in terms of y though, like x=4y

Eileen Sandoval

Best Of all the graphing apps I've tried, this one is the best. Its easily visible, it can graph linear equations, parabolas, hyperbolas, and it even shows the asymptotes

User reviews

Very few necessary functions This graphing programme might be useful for somebody doing GCSE or below. I opened it up and found that it only let's you put in graphs in the form f(x) and has very few functions I needed for graphs. The only reason to get a graphing programme is to get it to graph things you can't yet I believe I could do a far better job than this app. I was sorely disappointed in this app.

What's New

* Intersection finder revamped all around and fixed on later 4.x versions of Android

* Complete Holo UI update

FAQ’s

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?

A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/

Q. How do I get to the keys for pi, e, solve, etc?

A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.

Q. What do you have planned for future releases?

A. You can keep up to date on the latest news on our blog at http://mathally.blogspot.com/ . This news will include what is coming up in future releases. Also feel free to leave comments and let me know what you think!
