GeoGebra Book: Introduction to trigonometric graphs

[b]A geometric derivation of the basic trigonometric graphs from the unit circle. [/b] The unit circle, simply put, is the most basic circle you can get: the circle centred at the origin with a radius of 1. This is a very simple but very powerful mathematical concept, particularly when building up a conceptual understanding of trigonometry. Explore each applet in turn to build up a natural picture of the basic trigonometric graphs (sine, cosine and tangent), before extending into a consideration of transformations. Questions follow each applet to structure your consideration of each graph alongside the unit circle.
