Two more destroyers were trailing black smoke, moving at only half speed. They were maneuvering in a counterclockwise circle around Yamato, adding their guns to the collective fire.

另两艘驱逐舰也冒着长长的黑烟，航速只有先前的一半，它们行驶过来后呈逆时针方向环绕大和号，以便集中对空火力。

Now, the range of values for t, well, we are going counterclockwise around the entire circle so that should go from zero to 2pi.

这就变成了关于t的积分，这是一个逆时针旋转的整圆,那么t就是从0到2π
