(Another Classic Story Problem: Bearings) In this series of exercises we introduce and work
with the navigation tool known as bearings. Simply put, a bearing is the direction you are
heading according to a compass. The classic nomenclature for bearings, however, is not given
as an angle in standard position, so we must ﬁrst understand the notation. A bearing is
given as an acute angle of rotation (to the east or to the west) away from the northsouth
(up and down) line of a compass rose. For example, N40◦ E (read “40 east of north”) is a
bearing which is rotated clockwise 40◦ from due north. If we imagine standing at the origin in
the Cartesian Plane, this bearing would have us heading...
