1. Abstract
The Scientific Graphing and Calculation Application is a web-based tool developed using React.js that combines graph plotting and mathematical computation in a single interface. This application integrates a graphing system powered by the Desmos API along with a scientific calculator to perform complex calculations.
The graphing component allows users to visualize mathematical functions dynamically, while the calculator enables users to evaluate expressions efficiently. The system also incorporates algorithms such as infix to postfix conversion and postfix evaluation (Reverse Polish Notation) to process mathematical expressions accurately.
This project demonstrates the integration of third-party APIs and algorithmic logic in React.js to build an interactive and educational mathematical tool.
2. Objectives
The main objectives of this project are:
3. Existing System
Existing systems for graphing and calculation include:
• Standalone scientific calculators
• Graphing calculator software
• Online mathematical tools
Limitations of Existing Systems
4. Proposed System
The proposed system is a Scientific Graphing and Calculation Application that integrates both graph plotting and calculation features in a single platform.
In this system:
• Users can input mathematical expressions.
• Graphs are plotted dynamically using the Desmos API.
• A calculator evaluates expressions efficiently.
• Algorithms handle expression conversion and evaluation.
• The interface is divided into graphing and calculation sections.
This system provides a unified and interactive solution for mathematical analysis and visualization.
