**function**defined, for all x in, by Then, F is continuous on, differentiable on the open interval (a, b), and for all x in (a, b) ... Let f be a real-valued

**function**defined on a closed interval that admits an antiderivative g on ...

... For instance, a sequence of

**functions**can frequently be constructed that approximate, in a suitable sense, the solution to a problem ... Then the integral of the solution

**function**should be the limit of the integrals of the approximations ... However, many

**functions**that can be obtained as limits are not Riemann integrable, and so such limit theorems do not hold with the Riemann integral ...

... cannot be found exactly, some require special

**functions**which themselves are a challenge to compute, and others are so complex that finding the exact ... divides the integration range into, say, 16 equal pieces, and computes

### Famous quotes containing the word function:

“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot *function* without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”

—Howard Brenton (b. 1942)

“The mother’s and father’s attitudes toward the child correspond to the child’s own needs.... Mother has the *function* of making him secure in life, father has the *function* of teaching him, guiding him to cope with those problems with which the particular society the child has been born into confronts him.”

—Erich Fromm (1900–1980)

“The uses of travel are occasional, and short; but the best fruit it finds, when it finds it, is conversation; and this is a main *function* of life.”

—Ralph Waldo Emerson (1803–1882)
