OK, so let me show you a nice example of why we might want to use vectors to study parametric curves because, after all, a lot of what's here you can just do in coordinates.

我来举个例子，解释为什么我们用向量来学习参数曲线，毕竟我们学了这么多的都只能在坐标上完成。

The following example show you how to use regular expressions to extract concepts such as coordinates and areas from text.

下面的示例演示如何使用正则表达式从文本中提取出坐标和面积等概念。

So while Stone occasionally directed episodes in the early years of the show, he's found his niche as the person who coordinates the episodes, making sure they arrive on time and under budget.

所以，虽然斯通在节目的早年偶尔负责导演，他发现更适合他的还是整合每一集，确保能在预算之内按时交货。
