Hey, thanks for the feedback! Glad to hear the trig article helped (one of my favorite aha moments -- all the trig functions, including stuff like the exotic cosecant, can be drawn together.)<p>I&#x27;m a fan of Tau as an interesting simplifying concept but don&#x27;t think mentions of pi should necessary be removed. My intuition is that radians are &quot;distance traveled&quot; as you go along a circle. Pi is the &quot;neutral to max to neutral&quot; distance and Tau is the full cycle (neutral, max, neutral, min, neutral). Ideally we just think about &quot;distance&quot; and context determines whether we want the journey to be &quot;there and back&quot; or just &quot;there&quot;.
