The percentages detail is very cool, never thought about it! I also think of sin&#x2F;cos as percentages, but there&#x27;s one small detail that can be easy to miss. While sine and cosine generate &quot;percentages&quot; between -1 and 1 they don&#x27;t generate them uniformly, because their derivative is not a linear function! If we were to sample sine or cosine between 0 and PI at uniform intervals we would see that the percentages would &quot;cluster&quot; around the peaks and valleys because that&#x27;s where the function &quot;decelerates&quot; (or the derivative decreases).<p>This bit me once!
