## LaTeX

- Inline LaTeX: \\[ \\frac{d}{dx} \\left( \\frac{x-438}{x^2+23x-7} \\right) = \\frac{-x^2 + 869}{(x^2+23x-7)^2} \\]

- Block LaTeX:
|
|
\`\`\`latex
|
|
\\frac{d}{dx} \\left( \\frac{x-438}{x^2+23x-7} \\right) = \\frac{-x^2 + 869}{(x^2+23x-7)^2} \\\\ → \\\\ cos(2x) = 2cos^2(x) - 1 = 1 - 2sin^2(x) = cos^2(x) - sin^2(x)
