Our online calculators, developed by Amir Rashedi, including the current version of our online graphing calculator, are the recreations of the calculators originally written as Java applets and hosted on the now-defunct Yahoo! GeoCities (Web Archive - GeoCities-graphing calculator). These Java applets had a significant impact on the development of online calculators.
Our online graphing calculator introduced a novel method for graphing mathematical expressions. Prior to its introduction, other graphing tools employed a tedious and restrictive method to graph functions. Users were required to manually scale the fixed width and height of the canvas and set minimum and maximum values for each dimension to display the graph. This approach limited the flexibility and accuracy of graphing, making it an inefficient and frustrating process.
Our graphing calculator pioneered a new and user-frienly approach, which other developers adopted soon after the release of our Android version. It graphed functions on a intelligently specified default domain, which could easily be modified as desired, resembling the traditional approach used on paper.
Furthermore, our Cartesian and polar graphing calculator recognized that relevant mathematical expressions can be graphed in both Cartesian and polar coordinate systems, dispelling the common misconception that functions are rigidly categorized as either "Cartesian functions" or "polar functions".
Additionally, our graphing calculator was the first to allow users to animate polar graphs of functions. It also was the first, and remains the only graphing calculator to date capable of graphing polar parametric curves. Furthermore, our graphing calculator can animate the construction of parametric curves in both Cartesian and polar coordinate systems. These innovative features allowed users to witness the creation of these polar function graphs and parametric graphes step-by-step for the first time ever in the most natural way available anywhere.
Moreover, our graphing calculator was the first online tool to introduce graphing capabilities for general equations, that can contain both independent and dependent variables on both sides, thus making it possible to graph implicitly defined functions too.
Our graphing calculator is also the only one to have an integrated derivative calculator. This derivative graphing calculator is capable of calculating symbolic derivatives of functions and parametric expressions and graphing them.
Our graphing calculator in Java was the first to graph in oblique coordinate systems, allowing users to rotate axes and automatically regenerate the graph accordingly. The current HTML and JavaScript version remains the only graphing calculator with this feature to date.
We also developed the first online matrix calculator capable of handling complex matrices, which contain complex numbers as their elements.
Other calculators that you can find on our website include a scientific calculator capable of handling complex numbers and a partial derivative calculator, capable of calculating ordinary derivatives of single-variable functions and partial derivatives of multiple-variable functions with respect to any of its independent variables.
Our calculators have transformed the way mathematical expressions are graphed and analyzed, offering users a comprehensive and intuitive set of tools for exploring the intricacies of mathematics. From introducing novel graphing methods to enabling the animation of polar graphs and parametric expressions, our calculators have pushed the boundaries of mathematical exploration, making complex concepts more accessible and engaging for learners of all levels. As we continue to innovate and develop new functionalities, our calculators remain committed to empowering users to delve deeper into the fascinating world of mathematics.
