Symbols:V
Roman Numeral
- $\mathrm V$ or $\mathrm v$
The Roman numeral for $5$.
Its $\LaTeX$ code is \mathrm V or \mathrm v.
Closed Set
- $V$
Frequently used, and conventionally in many texts, to denote an closed set in the context of topology.
The $\LaTeX$ code for \(V\) is V .
Variance
- $\var X$
Let $X$ be a discrete random variable.
Then the variance of $X$, written $\var X$, is a measure of how much the values of $X$ vary from the expectation $\expect X$, and is defined as:
- $\var X := \expect {\paren {X - \expect X}^2}$
That is: it is the expectation of the squares of the deviations from the expectation.
The $\LaTeX$ code for \(\var X\) is \var X .

Velocity
- $\mathbf v$
The usual symbol used to denote the velocity of a body is $\mathbf v$.
Its $\LaTeX$ code is \mathbf v .
Speed
- $v$
The usual symbol used to denote the speed of a body is $v$.

Its $\LaTeX$ code is v .
Volt
- $\mathrm V$
The symbol for the volt is $\mathrm V$.
Its $\LaTeX$ code is \mathrm V .
Normal Volume
- $V_0$
The symbol for normal volume is $V_0$.
