I don't see it that way at all. I think it's a sinecurve, like most of our lives.
我并不这样认为，我认为那是一个正弦曲线，就像大部分人的人生一样，有起有伏。

This article puts foward a "Secant One—wave Sine—shaped Transition Curve", whose deflection angles are of secant varlation.
同时，建立了反余弦一波正弦形缓和曲线的设置方法和计算公式。

Meanwhile, under two-group instability modes, it is discovered that the curves between electric power of generator unit and rotator's angle in relative to center of inertia is a sinecurve.
