Partial derivative

In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables with the others held constant. They are useful in vector calculus and differential geometry.

The partial derivative of a function f with respect to the variable x is represented as rac{ partial f }{ partial x } or partial_xf or fx (where partial is a rounded 'd' known as the 'partial derivative symbol,' which coincides with the cursive Cyrillic letter "de" and is pronounced as its English counterpart "d" - that incidentally was the notation first introduced by Legendre).
