Progress and Issue Tracking

Current Issues (April 6, 2025)

Deep Learning Animation Error:
- Status: ✅ Fixed
- Error was: undefined is not an object (evaluating 'nodes[connIndex].x')
- Location: Neural network animation in Deep Learning page
Differentiation Content Not Showing:
- Status: ✅ Fixed
- Issue: Only integration tab was working in Calculus page
- Fix: Resolved syntax error (extra closing brace) and fixed tab navigation buttons
Missing Content:
- Status: ✅ Fixed
- Series and Sequences section implemented with interactive visualizations
- Linear Algebra visualizations implemented:
  - Matrix Operations (addition, multiplication, determinant, inverse)
  - Linear Transformations (rotation, scaling, reflection, shear)
  - Eigenvalues & Eigenvectors visualization
Navigation Issues:
- Status: ✅ Fixed
- Deep Learning now appears properly in dashboard/main navigation
Navigation Scalability:
- Status: ✅ Implemented
- Better nav organization with folding/dropdown functionality

✅ Review all visualizations to ensure proper functionality
✅ Implement all "coming soon" visualizations in most important sections
Enhance mobile responsiveness of visualizations
Improve loading states for large visualizations
Add additional interactive elements to existing visualizations
Implement remaining "coming soon" visualizations in secondary sections:
- Statistics/Regression page
- Number Theory page

April 6, 2025:
- Implemented three Linear Algebra visualizations:
  - Matrix Operations with dynamic matrix sizing and operations
  - Interactive Linear Transformations with real-time visual feedback
  - Eigenvalues & Eigenvectors visualization with animation capabilities
- Implemented Series & Sequences visualization with interactive controls for different sequence types
