Note: The delimiters are automatically sizes. |

Delta (upper case greek letter) $$\Delta$$ gives |
|
delta (lower case greek letter) $$\delta$$ gives |
|
div (division) $$x\div~y$$ gives |
|
double vertical line (norm symbol) - Syntax: \left\|...\right\|
- Exp.: $$\left\|af\right\| = \left|a\right|\left\|f\right\|$$ gives
