## How to Use the Advanced Math Tutor |
|
|
|
|
|
### Key Features 🎉 |
|
|
- **Professional math rendering**: All equations rendered using MathJax/LaTeX |
|
|
- **HTML-formatted solutions**: Beautiful, readable format |
|
|
- **Download HTML**: Save solutions as HTML files with proper math notation |
|
|
- **Download PDF**: Convert solutions to PDF (Note: PDF math rendering may vary) |
|
|
- **Print functionality**: Print directly from your browser |
|
|
|
|
|
### Getting Started |
|
|
|
|
|
#### For Text Problems (OpenRouter) |
|
|
1. Get API key from [OpenRouter](https://openrouter.ai/) |
|
|
2. Enter your problem in proper notation |
|
|
3. Get beautifully formatted solutions with proper mathematical notation |
|
|
|
|
|
#### For Image Problems (Together AI) |
|
|
1. Get API key from [Together AI](https://www.together.ai/) |
|
|
2. Upload a clear image of the math problem |
|
|
3. Optionally add context |
|
|
|
|
|
### Math Notation Tips |
|
|
- Superscripts: x² or x^2 |
|
|
- Subscripts: x₁ or x_1 |
|
|
- Fractions: Use / or describe as "numerator over denominator" |
|
|
- Greek letters: pi, alpha, beta, theta, etc. |
|
|
- Square roots: √ or sqrt() |
|
|
|
|
|
### Types of Problems |
|
|
- Algebra, Calculus, Trigonometry |
|
|
- Geometry, Statistics |
|
|
- Number Theory, Linear Algebra |
|
|
- And much more! |
|
|
|
|
|
### Note on PDF Export |
|
|
The HTML version will always have perfect math rendering. The PDF export uses |
|
|
WeasyPrint which may have limitations with complex math notation. For best results, |
|
|
use the "Print to PDF" button in the HTML view instead. |
