# 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.

Why can't plot circle? (x+3)^2+(y+5)^2=9 is equal to y=±sqrt(9-(x-3)^2)-5, just enter 2 equation(±, so one +, and one -) and plot it, you will find the circle

Jarvan Lightshield

Wonderful Simple to use and perfect for anything math related you could need in school and more than that. If you really need to plot circles I would assume you use different software on the PC like GeoGebra or something. You can plot multiple graphs in different colors and find intersections. The only thing missing would be being able to input fractions as actual fractions instead of using parentheses and the division symbol but that can be overlooked. (Also no y variable)

Benjamin Kollar

Useful,but room for improvment The square root of a number has two valuse,one positive and one negative. Grapher only takes into account the positive value so when plotted it will not give the proper graph. Also, the input is basic for example a fraction has to be entered in the form of a divide sign this makes the equation harder to read. if input is familiarised and fixed square root problem will rate 5 stars

Great and simple Would like 0.1 for coarse and 0.01 for fine x axis steps instead of irregular intervals. Other then this excellent app. Thanks!

Very good ! I recommend 100% Very good and sooo practical!Now i can verify very easily if i made my graphs right !

Has an excellent interface n does everything that one wants to do with graphs!! Love it Has an easy interface, allows more than 1 graph simultaneously, has diff colours, works well n looks good 😎

Really good app If you need to do graphics, just put it in. It will precisely show you what you need. It has a very clean and beautiful design and it's very easy to use. The only thing that saddens me it's the fact it can't do even more. Some graphics it just can't do. But yes, definitely recommend!

OK, but major flaws Firstly, there is the fact all equations must be equal to f(x) , excluding the possibility of drawing circles. Secondly, the intersection finder just finds the intersection on the screen, then works out the coordinates from that, making it close, but wrong. For example the solution to f(x)=x, f(x)=0 was 0.003877, 0.001912, not (0,0).
