## Derivative

In calculus, a branch of mathematics, the **derivative** is a measure of how a function changes as its input changes. Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity; for example, the derivative of the position of a moving object with respect to time is the object's instantaneous velocity.

### Famous quotes containing the word derivative:

“When we say “science” we can either mean any manipulation of the inventive and organizing power of the human intellect: or we can mean such an extremely different thing as the religion of science the vulgarized *derivative* from this pure activity manipulated by a sort of priestcraft into a great religious and political weapon.”

—Wyndham Lewis (1882–1957)

“Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some *derivative* old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.”

—Henry David Thoreau (1817–1862)
