What is the LaTeX Mu?

Mu is the twelfth letter of the Greek alphabet. In mathematics, it represents the mean (average) of a distribution. In physics, it often represents the coefficient of friction. In SI units, the micro prefix (μ) represents one millionth.

Common Use Cases

The Mu symbol is commonly used in the following contexts:

Mean/Average

Represents the mean of a distribution.

Code

Mean: $\mu = \frac{1}{n}\sum_{i=1}^{n} x_i$

Output

Mean: μ = (1/n)Σx_i

Coefficient of Friction

Used in physics for friction.

Code

Friction force: $F = \mu N$

Output

Friction force: F = μN

Micro Prefix

Represents one millionth in SI units.

Code

Wavelength: $\lambda = 650$ μm (micrometers)

Output

Wavelength: λ = 650 μm (micrometers)

Mean of Normal Distribution

Normal distribution using mu

latex

\documentclass{article}
\begin{document}

For a normal distribution with mean $\mu$ and standard deviation $\sigma$, the probability density function is:

$$f(x) = \frac{1}{\sigma\sqrt{2\pi}} e^{-\frac{(x-\mu)^2}{2\sigma^2}}$$
