This project focuses on the development of a scientific calculator using Java for the backend with Spring Boot, and HTML, CSS, and JavaScript for the frontend. The calculator provides essential arithmetic operations (addition, subtraction, multiplication, division) and advanced mathematical functions such as trigonometric calculations (sin, cos, tan), logarithmic functions (log, ln), exponentiation, and square roots. The frontend interface ensures a user-friendly experience, allowing users to input expressions directly. The backend developed using Spring Boot, processes these expressions by handling complex calculations and returning results to the frontend in real-time. This application demonstrates effective communication between frontend and backend through RESTful APIs, ensuring efficient performance and scalability. The project also emphasizes modular design, code reusability, and follows best coding practices with a structured approach to error handling and testing.
