Instead, formulas may be placed on their own line using < math display = block >. For instance, the formula above was typeset using <math display=block> \int _ 0 ^ \pi \sin x \, dx.</math>. If you find an article which indents lines with spaces in order to achieve some formula layout effect, you should convert the formula to LaTeX markup.
The norm of a vector is represented with double bars on both sides of the vector. The norm of a vector v can be represented as: ‖ ‖ The norm is also sometimes represented with single bars, like | |, but this can be confused with absolute value (which is a type of norm).
Some variants of X-bar notation use a double-bar (or double-prime) to represent phrasal-level units. X-bar theory derives its name from the overbar.
