Looking at our trig cheatsheet, we find an easy ratio where we can compare secant to 1. For example, secant to 1 (hypotenuse to horizontal) is the same as 1 to cosine: Suppose our secant is 3.5, i.e. 350% of the radius of the unit circle. What’s the angle to the wall?

Sep 19, 2007 · Last class period, my PreCalculus (juniors) and Trigonometry (seniors) built up an understanding of the unit circle through discovery. The basic idea of the activity was, according to one student, "if you choose one angle, and graph it in each quadrant, then the sin, cos, and tan values are the same in each quadrant, ignoring the plus and minus". You discover new ways to record solutions with interval notation, and you plug trig identities into your equations.
