This workbook produced by HELM is a good revision aid, containing key points for revision and many worked examples. Which shows that the order of differentiation does not affect the result. The partial derivative of a function $f(x,y)$ with respect to $x$ is denoted $\dfrac The process of finding a partial derivative is known as partial differentiation. It is computed by taking the first derivative of $f$ with respect to $x_1$ whilst holding all other variables $x_2,\ldots,x_n$ fixed, i.e. The following table documents the complete 24 letters (plus 1 archaic letter) of the Greek alphabet, along with each symbol’s case, English equivalent, example and usage. Given a function of two or more variables $f(x_1,x_2,\ldots, x_n)$, the partial derivative of $f$ with respect to $x_1$ gives the rate of change of $f$ with respect to $x_1$. Mathematics makes extensive use of Greek symbols to refer to key mathematical constants, variables, functions and other entities.
