Partial

Syntax
partial ( expression )
Implemented in iMath since version 2.2.0 or earlier.
Explanation
Create a partial differential, e.g. partial(x). Please keep in mind that though you can handle this object like a symbol, it does not always make mathematical sense!
If you want to create a partial differential of a function f (i.e. partial(f) / partial(x)), use PDIFFERENTIATE(f,x,1). iMath will automatically separate this into two differentials partial(f) and (partial(x))^{-1}, but will mark them as being connected, so that on printing they can be displayed correctly.
In other words, you should only use partial when it is really necessary.
