I am not fluent in the mathematical formula coding language "Tex" or any of its offshoots. They are used in [[Notion]] and [[Obsidian]] for writing math. I always have to look stuff up. This is a very incomplete syntax cheat sheet. # Basics - `$`- Math delimiter, place on both sides - `\` - the main escape character, saying "this is special" - `^` - superscript - `_` - subscript - `{}` - partitioning syntax - `\times{text here}` - multiplication - `\frac{a}{b}` - fractions - `\sqrt{a} ` - square root - `\sqrt[n]{a}` - nth root - `\text{text here}` `$ a^2 = \frac{x_a}{\sqrt{x_b}} \text{ means nothing} $` $ a^2 = \frac{x_a}{\sqrt{x_b}} \text{ means nothing} $ # Equivalency - `\le` - less than equal to - `\ge` - greater than equal to - `\approx` - approximate - `\equiv` - equivalent `$ a \le b \ge c \approx d \equiv e $` $ a \le b \ge c \approx d \equiv e $ # It's all Greek to me - `\alpha` - all greek letters - `\infty` - infinity `$ \alpha = \beta + \gamma < \infty $` $ \alpha = \beta + \gamma < \infty $ # Big Operators - `\sum` - sum sign - `\int` - integral sign - `\leftarrow` & `\Leftarrow` - arrows, capitalized is thicker - `\rightarrow` & `\Rightarrow` - arrows, capitalized is thicker - `\leftrightarrow` & `\Leftrightarrow` - arrows, capitalized is thicker `$ \sum{a, b} \Leftrightarrow \int{3x+3 dx} $` $ \sum{a, b} \Leftrightarrow \int{3x+3 dx} $ **** # More ## Source ## Related
