WebJun 29, 2024 · What I’m describing, finer and finer sums of f (t) for a sample of t from the input range, is an integral of f (t) from 0 to 1. c_0 = \int_ {0}^ {1} f (t) dt c0 = ∫ 01 f (t)dt. Normally, since the aim is to compute an average, you’d divide this integral by the length of the interval. But that length is 1, so it amounts to the same thing. rankin food martWebFeb 25, 2024 · Etymology [].
