Determinants

This is a chapter-wise rendering test file. It is not a full textbook chapter. It contains representative formulae, equations, diagrams, mechanisms, tables, and notation patterns useful for testing digitised CBSE/NCERT-style content.

Metadata

Key rendering targets

• Inline formulae like $E=mc^2$
• Block formulae using $$
• Tables
• Diagrams using Mermaid
• Searchable plain text
• Future conversion to HTML, JSON, database, and app content

Determinant rendering

$$\begin{vmatrix} a&b&c\\ d&e&f\\ g&h&i \end{vmatrix} =a(ei-fh)-b(di-fg)+c(dh-eg)$$ $$A^{-1}=\frac{1}{|A|}\operatorname{adj}(A)$$

Practice/testing prompts

1. Check if all formulae render correctly.
2. Check if the diagram appears in Obsidian or HTML.
3. Mark this chapter as pass, needs-plugin, or needs-SVG.
