‘end—point’ behaviour by considering the limiting values (from inside I ), and/ or
using the First Derivative Test to determine the nature of any critical numbers
in I. For problem 22 use the Closed Interval Method] EXTRA PROBLEMS: E8.1* Telegraphs were originally transmitted in Morse Code, a series of short (dots) or long
(dashes) signals representing the letters of the alphabet. If the fraction of dots and
dashes per unit time are a: and 1—x respectively, where 0 < x < 1, then the information content is given by
[(93) = —xlnx —— (1 —— as)ln(1 — :13). a) Show that [(1') > 0.
b) Find the value of m which maximizes [(1) c) Discuss brieﬂy how the result in b) might be useful. ...
