Description

Algorithmic Graph Theory application with option to export to TiKZ and

Metapost and send source code by email and copy to clipboard.

Metapost and send source code by email and copy to clipboard.

Graph theory and algorithm application. This app lets you create and

edit undirected simple graphs, as well as analyze properties of the

graph, and furthermore allows you to export the graphs in Tikz and

Metapost format.

The app has several built-in algorithms, especially exact NP-hard

problems like (Connected) Vertex Cover, Clique, Independent Set,

Dominating Set, Odd Cycle Transversal, Feedback Vertex Set, Steiner

tree, Minimum fill-in, Treewidth, Bandwidth, and other "simpler"

problems, like connectivity, diameter, girth, cut vertices and

bridges.

What's not to like If you are into graph theory (that's a finite mathematic), this is the Google Play toy of choice. You can make your graphs very simply and easily. And then you can use the world's longest settings menu to analyze them in about a gazillion ways. This would have been very nice to have back when I was studying mathematics. All we had was paper, pencil and our head. This is much prettier.

Amazed This app must have been written by serious mathematicians, thanks for a great tool. Took a few minutes to figure out how to use. Girth didn't work for my huge graph (160+ edges). I'm still amazed. Does things I've only dreamed of.

amazing this is very well made. I tried several apps and this was the best

Looks awesome Works great! Get to use the entire surface for drawing! The interface is quite intuitive and takes just a few second to figure out. Good idea!

good! Its nice but the text is really small with the resolution on my galaxy s3

What's New

Listen Read Device Only Added Installed You can draw a graph of any function as simple 2-D or 3-D.

After that, You can draw graphs of functions that you wonder as you want.

In 2D mode or 3D mode, you can draw easily many graphs.

This is a fun job if you prefer. I wonder how the graphs of functions change when the function's parameters change.

This is a fun job if you prefer. I wonder how the graphs of functions change when the function's parameters change.

Normal functions, logarithmic functions, exponential function, the absolute value function, trigonometric functions, inverse trigonometric functions, and many more can easily draw a graph of the function.

In three-dimensional graphics, sphere, Moebius strip, Cone, and many more can draw graphs of three-dimensional shapes.

Instructions -------------------------------------------------------------------------------------------------

To use simple graph write your function in to the f(x) box and tap to Draw Graph button.

To draw a 3D graph write your functions parameters in to the boxes ( x, y, z ) and tap to Draw Graph button.

( Use "s" and "t" as parameter. )

If you want to see different 3D shapes then you can use Auto Graph button. There are several examples to see.

To write your function you can use that symbols ;

sin, cos, tan, ln, sqrt, abs, acos, asin, atan , ceil, floor, round, max, min, plus, minus, mul, div, pow,

. ,

^ , POWER

* , MULTIPLICATION

+ , ADDITION

Listen Read Device Only Added Installed Learn about linear graphs and vectors simply by just a swipe. Select graphs or vectors on intro page.

Find the relationship between lines, gradients, vectors and equations by drawing a graph with your finger while this app does the rest.

No input of values is necessary. This is an automatic graph app.

Math Graph app – you draw graph, it works out the equation for you.

Trace the graph with your finger. When done, sit back and

study your graph.

The app will draw the line and calculate gradient.

It will also write down the graph equation at bottom left of screen.

On vectors screen, you draw vectors with your finger, and this app analyzes them for you. It is an easy way to learn about simple vectors including addition of vectors.

This native math app is meant for beginners in graphical methods, the first 2 years of learning graphs.

If you have studied complex graphical methods but would still like to remind yourself about the basics, this app will do just that.

You can work with the equations produced at your leisure, re-arranging them to discover more about graphical maths.
