Vitalik Buterin: 尖峰来自与圆比的良好近似： 11/7 ~= tau/4（或 pi/2） 11 ~= 7/4 * tau（一整圈加上 270.25’） 所以 tan(11) 很高：-225.95 355 和 710 附近的尖峰是 11/7 的“回声”，因为 355/113 是 tau/2 的*惊人*近似值

原推：The spikes emerge from good approximations to the circle ratio:

11/7 ~= tau/4 (or pi/2)

11 ~= 7/4 * tau (one full rotation plus 270.25′)

So tan(11) is high: -225.95

The spikes near 355 and 710 are “echoes” of 11/7 created because 355/113 is an *amazing* approximation of tau/2
