This applet identifies line segments defined by the unit circle whose lengths correspond to the six basic trig functions. This also illustrates several of the most common trig identities.
1) What relationships between the trig functions do you notice?
2) Can you prove the segments are actually the lengths they are labeled?
3) What trig identities do you see?
