Most people groan when they think of Trigonometry. In the book October Sky, by Homer Hickman, a group of kids had to teach themselves trig, calculus and physics in order to participate in a science fair that opened the door to their future. Trigonometry is used in navigation, physics, construction and other fields. The word trigonometry came from two Greek words, trig, meaning triangle and metra meaning measurement. Basically, trigonometry is the study of the relationships among the angles and sides of triangles. Maybe the biggest hurdle in learning trig is, knowing all the terms.
