Excellent! Low ratings due to misunderstanding what it is? Hoping for more features for network analysis, but the algorithmic stuff is first-rate. Interface is simple and easy to use.

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.

User reviews

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

## Graphing Calculator by Mathlab

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

## Desmos Graphing Calculator

At Desmos, we imagine a world of universal math literacy and envision a world where math is accessible and enjoyable for all students. We believe the key is learning by doing.

To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Sliders make it a breeze to demonstrate function transformations. It's intuitive, beautiful math. And best of all: it's completely free.

Features:

Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time - and you don’t even need to enter expressions in y= form!

Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph

Tables: Input and plot data, or create an input-output table for any function

Statistics: Find best-fit lines, parabolas, and more.

Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window.

Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger.

Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more.

Inequalities: Plot cartesian and polar inequalities.

Offline: No internet access required.

GraphIt is a utility that is used to display on a Cartesian plane any mathematical function, which can be f(x)=2, f(x)=2*x, f(x)=sin(x) ecc... The management function is entrusted to you: you can add more or modify existing ones.

The integration of functions is facilitated by self-completion of statements, also expressions of the interpreter is very flexible and allows the inclusion of any function: even the most complex are recognized and interpreted correctly.

The main functions recognized are: abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), avg(x1,x2,...,xN), ceil(x), combin(x,y), cos(x), cosh(x), e(), exp(x), fact(x), floor(x), lg(x), ln(x), log(x,y), max(x1,x2,...,mN), min(x1,x2,...,xN), mod(x,y), pi(), pow(x,y), rand(), sign(x), sin(x), sinh(x), sqrt(x), sum(x1,x2,...,xN), tan(x), tanh(x), toDeg(x), toRad(x).

The graph allows an accurate view of the trend of function at any point in the plane. You can zoom and pan through the classical gestures.

There is also a tool which can calculate the value of the functions included, given the value of x (via a number or expression).

## Data Structure and Algorithm

This application help you guys to quick brush up before interview on searching and sorting techniques.It includes all possible sorting (like; Bubble sort, Quick sort, Merge sort, Heap sort) and searching(like; Linear search,Binary search, Hashing) techniques. Apart from these algorithms it has also basic C programs which are frequently asked in interview for a fresher level and college based computer labs.

All the algorithms has been described in better understanding way and how it works. All algorithms are also coded in C with a good example. All code has been executed successfully, so these are zero error codes.

The TI-82 is designed for algebra and trigonometry. Graph and compare functions, perform variable substitution, and solve single variable equations.

The TI-83 is designed for statistics and trigonometry. Graph and compare functions, and perform data plotting and analysis.

The TI-85 is great for engineering and computer science. Graph and compare functions, perform bit manipulation and convert between numeric bases.

The TI-86 is great for engineering and calculus. Graph and compare functions, perform bit manipulation and convert between numeric bases. Solve differential equations, plot vector fields.

All models allow you to write programs in TI-BASIC and perform basic scientific calculator operations.
