… LaTeX rendering fixes - Complete enhancement of Document 03 Trigonometric Identities with integrated TODO content - Add comprehensive geometric derivations for addition formulas using unit circle approach - Integrate co-function, periodicity, quadrant, and inverse function identity sections - Add double-angle and half-angle formulas with worked examples - Include educational cross-references to MathWorld for advanced learning - Standardize all degree symbols from Unicode ° to LaTeX ^\circ for KaTeX compatibility - Fix LaTeX rendering issues: \arccot function notation, inequality symbols, missing ranges - Apply Unicode symbol standardization across all three trigonometric documents - Update index.md to reflect completion of trigonometric documentation enhancement - Ensure all mathematical expressions render properly in documentation build system
- Add Example 4 demonstrating cosine difference formula: cos(15°) = cos(45° - 30°) - Remove duplicate content that was incorrectly placed at top of document - Complete the Examples of Addition Formulas section with both addition and subtraction cases - Ensure comprehensive coverage of trigonometric addition/difference formulas with worked examples
