Well, square
嗯正方形───Well, square
OK. And how do I create them? Well, the representation is, following a square bracket, followed by a sequence of elements, separated by commas, followed by a closed square bracket.───一个有序的序列,好,那么我们怎么创建元组呢?,好,表达式是,一个方括号,后面是一系列的元素,以逗号分开,以一个闭方括号结束,这就是我刚才所说的。
efficient sailing downwind or well off the wind, square sails do not generate power from their leading edge as in the Bermuda rig, which has become predominant in modern times.───帆船在顺风或无风航行时十分高效,它们逆风行驶时从帆前缘得到的动力却不如百慕大帆多,而帆前缘的动力在现代成为了主要动力。
we could try to minimize a square error like we did before.───我们可以试着最小化这个平方误差。
