The **partial derivative of $f$ with respect to $x_i$ at $a$** is denoted and defined as:

- $\dfrac {\partial f}{\partial x_i}(a) := g_i'(a_i)$

where:

- $g_i$ is the real function defined as $g \left({x_i}\right) = f \left({a_1, \ldots, x_i, \dots, a_n}\right)$
- $g'(a_i)$ is the derivative of $g$ at $a_i$.
