A trigonometric angle converter and reference tool. # Angle & Trigonometry Converter: The Ultimate Mathematical Reference Tool Unlock the full potential of your mathematical and engineering workflows with the **Angle & Trigonometry Converter**, a comprehensive, precise, and user-friendly Chrome extension designed for students, professionals, and math enthusiasts alike. Whether you're solving complex calculus problems, designing architectural blueprints, or simply brushing up on your geometry, this tool provides everything you need in one lightweight package. ## Precision Meets Simplicity In the world of mathematics, precision is paramount. The Angle & Trigonometry Converter delivers results with up to 10 decimal places, ensuring that your calculations are accurate enough for even the most demanding technical tasks. We understand that a tool is only as good as its usability, which is why we've focused on a minimalist, modern interface that stays out of your way while providing instant feedback. The interface is designed to be intuitive, requiring zero learning curve—just open and calculate. ## Key Features at a Glance ### 1. Multi-Unit Angle Conversion Gone are the days of manual conversion formulas. Our tool allows you to seamlessly switch between four primary angular units, catering to various scientific and industrial standards: - **Degrees (°):** The standard unit for geometry, navigation, and everyday applications where a circle is divided into 360 parts. - **Radians (rad):** The essential unit for calculus, physics, and advanced mathematics, where the angle is measured by the arc length on a unit circle. - **Gradians (grad):** A decimal-based unit frequently used in surveying and civil engineering, dividing a right angle into 100 parts. - **Turns (turn):** A natural unit for rotational mechanics, periodic functions, and cycle-based calculations, where one turn equals one full revolution. Simply enter a value in any unit, and see the equivalents in all other units updated in real-time. This eliminates the risk of calculation errors during manual conversions. ### 2. Comprehensive Trigonometric Calculator Calculate all six fundamental trigonometric ratios instantly for any angle. This goes beyond the basic sin/cos/tan found on most calculators: - **Sine (sin)** and **Cosine (cos)**: The foundation of wave mechanics and circular motion. - **Tangent (tan)** and **Cotangent (cot)**: Vital for slope analysis and triangulation. - **Secant (sec)** and **Cosecant (csc)**: Frequently used in integration and complex engineering formulas. The calculator handles edge cases gracefully, such as identifying undefined values (represented by the infinity symbol ∞) for functions like tangent or cosecant at specific angles (e.g., tan 90°), preventing "NaN" or error messages that interrupt your flow. ### 3. Inverse Trigonometric Calculator Need to find an angle from a ratio? Our inverse calculator computes: - **Arcsine (asin)** - **Arccosine (acos)** - **Arctangent (atan)** Enter a value between -1 and 1 (for asin/acos) or any real number (for atan) and get the resulting angle in both degrees and radians simultaneously. This dual-output feature is a massive time-saver for students who often need to provide answers in a specific unit for their homework. ### 4. Interactive Unit Circle Reference Visualize the relationship between angles and coordinates with our built-in Unit Circle diagram. It features: - A clear, high-resolution SVG rendering that stays crisp at any size. - Labeled common angles including 0°, 30°, 45°, 60°, 90°, and all their quadrant equivalents (120°, 135°, 150°, 180°, etc.). - Dual labeling in both degrees and radians (e.g., 30° and π/6). - An intuitive layout that helps you internalize trigonometric values and the symmetry of the circle. ### 5. Radian-to-Degree Quick Reference Card For those moments when you need a quick lookup, our reference table provides a side-by-side comparison of common radian values and their degree equivalents. It covers everything from 0 to 2π, making it an indispensable study aid for trigonometry exams. The table is formatted for readability, allowing you to find the value you need in seconds. ## Advanced Use Cases ### For Web and Game Developers Working with CSS transforms or Canvas rotations? Most programming languages require radians for their math functions, but designers often think in degrees. Use this extension to bridge the gap instantly without writing temporary "console.log" statements to check your math. ### For Engineering and Surveying When working with gradients or slopes, the ability to quickly convert between gradians and degrees is essential. Our tool ensures that you can verify your field notes against digital designs with 100% confidence in the precision of the output. ### For Students and Educators Trigonometry can be a difficult subject to master. Having a visual reference and a multi-function calculator in the sidebar helps students verify their work as they solve problems. Educators can use it as a visual aid during online tutoring sessions to demonstrate the relationships between different trigonometric functions. ## Why Choose Angle & Trigonometry Converter? ### Smart Persistence We respect your workflow. The extension uses `chrome.storage.local` to remember your last-used values and unit selections. When you close the popup and reopen it later, your data is right where you left it. No more re-typing long decimal values every time you switch tabs. ### Privacy-First Architecture Your privacy matters. The Angle & Trigonometry Converter operates entirely locally within your browser. It does not track your browsing history, require access to your website data, or communicate with external servers. It is a pure utility tool that respects your digital boundaries. ### Lightweight and Fast Built with optimized JavaScript and CSS, this extension loads instantly and consumes minimal system resources. It won't slow down your browser or interfere with your other open tabs. ## How to Get Started 1. Click "Add to Chrome" to install the extension. 2.
