Symbols:Mu

Mu

Expectation

$\mu$

Often used to denote the expectation of a given random variable.

The $\LaTeX$ code for $\mu$ is \mu.

Linear Density

$\mu$

Used to denote the linear density of a given one-dimensional body:

$\displaystyle \mu = \frac m l$

where:

• $m$ is the body's mass;
• $l$ is the body's length.

The $\LaTeX$ code for $\mu$ is \mu.

Parameter of Poisson Distribution

$\mu$

Used as an alternative to $\lambda$ to denote the parameter of a given Poisson distribution.

The $\LaTeX$ code for $\mu$ is \mu.

Moment of Discrete Random Variable

$\mu'_n$

Let $X$ be a discrete random variable.

Then the $n$th moment of $X$ is denoted $\mu'_n$ and defined as:

$\mu'_n = E \left({X^n}\right)$.

where $E$ denotes the expectation function.

The $\LaTeX$ code for $\mu'_n$ is \mu'_n.
