Phillips Vector Anal. v. 101 Vectors which are only piecewise differentiable. 1939Mind XLVIII. 366 They have to proceed piece-wise, measuring every little line and bend. 1953L. V. Ahlfors Complex Anal. ii. 65 We shall say that the arc is differentiable if z′(t) exists and is continuous... An arc is piecewise differentiable..if the same conditions hold except for a finite number of values t. 1962Alley & Atwood Electronic Engin. xvi. 546 This method is known as the piecewise-linear method, since the tube or transistor is assumed to be linear over certain regions of operation. 1966Scott & Tims Math. Anal. vi. 209 It is useful also to consider functions which, while not continuous in a whole interval, are nevertheless made up of a finite number of continuous pieces. Such functions are called piecewise continuous. 1979Nature 12 Apr. 623/1 Their major effect is to re-order, piecewise, the fibre map of the eye circumference laid out across the t axis of the ribbon. |
