Acknowledgment of Problem
S ources
Virtually all of the problems in this book come from elsewhere. Some of
them I have gotten from colleagues and students, or from competitions and
examinations long since forgotten, so that I cannot now identify from where
they came. However, others have been deliberately drawn from specific
sources, which I would like to acknowledge.- Ontario Problems Papers. With the permission of the Ministry of Ed-
ucation and the Queen’s Printer of Ontario, the following are taken from
the Grade 13 Problems Examinations set annually by the Department of
