The function pdConv will then use Defer and TraditionalForm to display the result in desired conventional typesetting. In the particular case considered, pdConv will read indexes 0, 1, and 2 variables x, y, and z and function name f from the syntax provided by Derivative and put them in the syntax of function D. To better understand the structure of the function, consider the table below.
Great, but what if after some derivations we end up with an answer given in terms of indexed notation? How do we display it in terms of the symbol ∂? Well, we can construct a function that reads out the elements of syntax given by Derivative, puts them in the form of D, and applies TraditionalForm: The function Defer was used to prevent Mathematica from automatic evaluation from the syntax of function D to the one of function Derivative. We can learn from it that the notation we need can be provided by the function D:

The full list of Mathematica syntax that may be displayed via TraditionalForm as a conventional notation can be found in the extensive tables of the tutorial TraditionalForm Reference Information. Yet this is not what Jee is looking for, which is a convention that uses the symbol ∂. This is a type of traditional mathematical notation where partial derivatives are denoted by indexes in the function’s superscript. How does one go from this typesetting to other conventional mathematical notations? Well, we can start by using the function TraditionalForm, which was created exactly for this purpose: If one deals with differentiation of undefined functions, the output will always be of the form shown in the left column, dictated by the underlying syntax of the right column. Despite different appearances, the underlying expressions are of the same syntax, which can be revealed with the function InputForm: Take a look at the following list, where each element represents a different way differentiation can be entered:įor the last element we used the key sequence Esc + d + t + Esc. Yet they are all interpreted through the function Derivative, which is an equivalent of the differential operator in traditional mathematics. The typesetting in which derivatives are displayed in Mathematica may vary depending on the situation. To quickly catch up with the topic, one should read the recent Q&A blog post “ Three Functions for Computing Derivatives”. We will assume that the reader is already familiar with the basics of differentiation in Mathematica. Read below or watch this screencast for the answer (we recommend viewing it in full-screen mode): How can I transform the output of partial differentiation such as f (1, 0) to the mathematical form ?
