Strategy for finding half angle ratios
In this video, we'll look at strategies to find half angle trigonometric ratios using the same identities that we use to find double angle ratios. We do things in reverse! Some of these identities are easier to deal with while some aren't. We'll look at these strategies in detail while solving for tan(pi/8). Once we have the value, we'll form a ...
