discontinuous

Page numbers are for draft copy at present; they will be replaced with correct numbers when final book is formatted. Chapter numbers are correct and will not change now.

A curve or graph is said to be discontinuous if there are sudden jumps or gaps in value. For example, consider the function:
  nbsp; if x<=0 then 0 else 1
This has a discontunuity at x=0, the value just below is 0 and the value just above is 1.
