Definite integrals are integrals which have limits (upper and lower) and can be evaluated to give a definite answer. \[= \left[ {\frac{{ - 1}}{3}\cos (3x + \frac{\pi ...

P.S.—I thank Mr. C. F. Merchant for pointing out in NATURE of June 3 that the four-ordinate rule is already in use, and for giving a reference to Tchebycheff's rules, with which I was unacquainted.
