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。

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。

then, dA, so we had to use the product rule carefully, or we use the partials.───那么对于dA，我们必须谨慎地使用乘法法则，或用偏微分。

Well, then, dA, so we had to use the product rule carefully, or we use the partials.───那么对于dA，我们必须谨慎地使用乘法法则，或用偏微分。

The Improved Product Rule for Multimodal Information Fusion───多通道信息融合的改进乘积规则

In the thesis, syntax knowledge and grammar rules are abstracted from the modern Chinese grammar library, and the knowledge express method by product rule is anal sized systematically.
