Omega is a Computer Algebra System (CAS)
Explorer accessible via the internet from
desktop/laptop computers and mobile devices.
Its underlying CAS engine provides the user
with immense power in both algebraic
and numeric computing.
To use Omega, only a web browser is required. Omega user composes
and submits mathematical query using a calculator-like graphical user
interface. Upon submission, the query is processed by Omega's
CAS engine, and the result is displayed in text or graphic formats.
Using the built-in functions of the web browser, the output can be
exported for further manipulation.
Omega can be accessed from the following devices:
Desktop
Laptop
iPad/Tablet
Smartphone
Omega is compatible with the following web browsers:
Firefox
Safari
Chrome
IE
Opera
Currently, Omega uses the following CAS as its underlying engine:
Maxima
Omega has a calculator-like graphic user interface
Omega is intuitive and flexible
Look at the following example of solving a quadratic equation: x2-x-1=0:
Omega can visualize curves and surfaces
There are two dynamic plotting functions located on the arithmetic and common symbols keypad:
The 2D plot function enters a template in the input widow. The user can edit the functions
and adjust the plotting range. The following example shows how to plot function
x2-x-1 where x varies from -5 to 5:
3D plot function is similar to 2D plot function:
Omega function keys display mouse-over tool-tips description
Omega provides just-in-time Help for all the functions
Click on the function key will display just-in-time Help from the underlying
CAS engine in the output window. The Help content provides specific descriptions
of each function key, query composition syntax, and additional examples:
Users familiar with the CAS can turn off just-in-time Help by checking the box next to the Export option at the lower corner of the screen:
The button will turn into after it is clicked, indicating computation is in progress.
Click on will terminate a running process.
Omega incorporates powerful programming language
Program can be written in CAS engine-specific programming language:
The 2D plot function enters a template in the input widow. The user can edit the functions
and adjust the plotting range. The following example shows how to plot function
x2-x-1 where x varies from -5 to 5:
3D plot function is similar to 2D plot function:
Users familiar with the CAS can turn off just-in-time Help by checking the box next to the Export option at the lower corner of the screen:
The 
button will turn into 
after it is clicked, indicating computation is in progress.
