1、another way that you can find the dot product.───另一个定义,点积的方法。
2、And I can rewrite this in vector form as the gradient dot product the amount by which the position vector has changed.───可以把这些用向量形式重新写下来,就是梯度向量和位置改变量的点积。
3、But, you will see that notation somehow helps to make it more straightforward So, what is dot product?───但是你会发现,这个方FaHui让问题更简单,那么,什么是“点积”?
4、If I take the dot product But now, what does it mean that the dot product between OP and A is zero?───如果我用OP·A我就得到了,那么OP和A的点积是0代表了什么呢?
5、It's the dot product between the normal vector of a plane and the vector along the line.───这是平面法向量,和沿直线向量的点积。
6、Let us take a down-to-earth example of a dot product.───举一个点积的,现实例子。
7、Since scalars are independent of the coordinate system, the dot product of two vectors is called a scalar invariant.───因为标量与坐标系无关,故两个矢量的点积称为标量不变量。
8、That is the dot product.───这就是点积。
9、Also note that you can calculate the dot product only if the two vectors have the same number of components .───另外请注意,只有当两个矢量的组件数相同时,才能计算点积。
