personal_scientific_calc

Inspiration

As an engineering student who frequently uses a scientific calculator, I wanted to create a more tailored and feature-rich tool for my personal use. I aimed to combine the functionalities of traditional scientific calculators with modern web technologies to enhance my productivity and efficiency. What it does

The personal_scientific_calc application is a scientific calculator that provides robust calculation capabilities alongside a note-taking feature. Users can perform complex mathematical operations, including trigonometric and logarithmic functions, with support for different angle units (degrees and radians). The application also offers a session-based storage system, allowing users to save and retrieve previous calculations and notes. The interface is split into a calculator component on the right side and a note-taking area on the left side, with a navbar for easy access to session history. How we built it

The application was developed using React and Next.js, leveraging the app directory for efficient routing and component organization. For calculations, I utilized JavaScript’s eval function in combination with math.js to handle complex mathematical expressions. The application features session management and data retrieval using Convex, where useQuery is employed to fetch session data without handling loading and error states manually. The UI components were designed with a focus on user experience, providing a clear separation between the calculator and notes. Challenges we ran into

Handling angle units: Ensuring that trigonometric functions correctly interpret angles as degrees by default and can switch to radians when needed required careful attention to detail.
Session management: Implementing a reliable system for saving and retrieving session data while maintaining a seamless user experience was complex.
Error handling: Minimizing the need for manual error and loading state handling in useQuery while maintaining application stability was challenging.

Accomplishments that we're proud of

Successfully integrating a note-taking feature with a scientific calculator, offering a dual-purpose tool for users.
Creating a user-friendly interface with clear separation between calculator functions and session history.
Implementing angle unit handling in trigonometric functions to ensure accurate calculations based on user settings.

What we learned

Developing a scientific calculator with modern web technologies enhances productivity by providing a customized tool that fits specific needs.
