So, product rule is OK for taking the derivative of a dot product.
那么乘积法则对点乘求导没问题。
In Listing 1, a simple rule to match product Numbers of Thinkpad laptops is created from the URL rule definition.
在清单1中，以url规则定义为基础，创建一个匹配Thinkpad笔记本电脑产品号的简单规则。
OK, now, so there's an interesting thing to note, which is that we can use the usual product rule for derivatives with vector expressions, with dot products or cross products.
还有个很有趣的现象要注意一下，就是我们可以用乘积法则,对向量表达式求导，无论是点乘或叉乘。
