This page explains exactly how Visual Trigonometry Calculator works — what runs locally in your browser,
how trigonometric computations are handled, and what technologies power the site. We aim for full transparency to ensure user trust, accuracy, and educational value.
Privacy at a glance: All calculations occur directly in your browser.
We DO NOT store, log, or send your inputs or results to any external server.
1) Core Calculation Logic
Purpose: Calculates values for all standard trigonometric functions (sin, cos, tan, cot, sec, cosec) and their inverses (arcsin, arccos, arctan, arccot, arcsec, arccosec), supporting degrees and radians. The calculator handles angles, triangles, and function compositions to provide accurate results for educational and visualization purposes.
Note: No external math libraries are used; all logic is implemented natively in C# for precision and efficiency.
1.1 Implementation Summary
- Each trigonometric calculation is performed using optimized C# arithmetic and math functions.
- Supports both degrees and radians, including conversion between them for accurate computations.
- Handles inverse trigonometric calculations and provides precise floating-point results up to six decimal places.
- No external computational libraries are used — all formulas and calculations are implemented natively in .NET Framework.
2) Visualization Methodology
After calculations are completed, the results are displayed using dynamic, interactive graphs and visualizations.
Users can explore trigonometric functions, angles, and triangles visually.
The rendering is done through the <canvas> tag, which provides a smooth, real-time drawing experience directly in the browser without relying on heavy third-party libraries.
This ensures fast performance, precise plotting, and full compatibility across modern devices.
3) Application Stack
Frontend: ASP.NET (Web Forms), HTML5, CSS3, JavaScript
Language: C#
Database: Microsoft SQL Server (optional, for saving user accounts or general logs; no calculation data stored)
Target Framework: .NET Framework 4.8
Note: All user inputs for calculations remain local and are never stored on the server.
4) Accessibility & UX Notes
- Input fields allow users to enter angles, triangle sides, or function expressions for accurate trigonometric computations.
- Graphs and visualizations use high-contrast colors and clear formatting for improved readability.
- The UI meets accessibility standards, ensuring usability across devices and for learners with different needs.
5) Security & Integrity
- All user interactions and computations are performed locally in the browser.
- No cookies, session storage, or analytics are linked to individual calculation data.
- Results and graphs are generated in real time without sending data externally, maintaining privacy and integrity.
