# Product Rule

In calculus, the product rule is a formula used to find the derivatives of products of two or more functions. It may be stated thus:

or in the Leibniz notation thus:

.

In the notation of differentials this can be written as follows:

.

The derivative of the product of three functions is:

.

### Famous quotes containing the words rule and/or product:

Every man needs slaves like he needs clean air. To rule is to breathe, is it not? And even the most disenfranchised get to breathe. The lowest on the social scale have their spouses or their children.
Albert Camus (1913–1960)

...In the past, as now, [Hollywood] was a stamping ground for tastelessness, violence, and hyperbole, but once upon a time it turned out a product which sweetened the flavor of life all over the world.
Anita Loos (1888–1981)
