About This Lesson
<p>Here are two versions Excel spreadsheets that can be used to link trigonometric ratios from a unit circle to their graphs. By changing the angle give you can see how sine; cosine and tangent graphs are produced from the ratio’s of height and width from a unit circle. 1. trigonometry.xls = This handout produces both sine and cosine graphs together when the angle is varied. 2. trigonometryv2.xls = This handout produces all three trig function graphs seperately as the angle varies.</p>
Very impressive use of excel!
