Exact Values for Trig Functions
Today we were to make a chart of the exact values of all 6 trig functions for up to 360 degrees on the unit circle. I didn't really get how to do it at all, but then i found out that for the chart you are only ever going to be using 2 circles. a 45:45:90 triangle or a 30:60:90 triangle, depending which angle you're on. If its 45, 135, 225, or 315 degrees the triangle you will use is a 45:45:90 triangle, all the other angles are the 30:60:90 triangle.
