A few sessions ago the writer was presented with the problem of providing for one hour per week a course outside the normal Intermediate syllabus in Mathematics for a group of First Year engineering students. Knowing how the engineer thinks with pencil in hand, and uses the drawing-board for a variety of design calculations, the solution adopted was that of putting as much elementary mathematics as possible on the drawing-board. This article outlines the course, along with some additional related matter, and among the reasons which seem to justify publication are
(a) the author—and some at least of his students!—have enjoyed the work described;
(b) much of the subject-matter is not easy to find in English books;
(c) a number of illuminating sidelights are thrown upon topics of the “normal” mathematics course;
(d) it is believed that portions at least could be introduced with advantage into both pre- and post-certificate courses.
