This trajectory allows squid to cover the most horizontal distance possible over a typical several second flight.

这条轨迹允许乌贼在典型的几秒飞行中覆盖尽可能多的水平距离。

And the cosine of that angle will be equal to its horizontal distance from the center of the ring, divided by the ring's radius.

该角度的答案将是它的水平距离 环的中心，除以环的半径。
