| 1. | The dot product, being the product of three scalars, is a scalar .
点积是三个标量的乘积，所以是个标量。 |
| 2. | Use the vector dot product to find the obtuse angle between two diagonals of a cube .
用矢量点积求立方体的两条对角线所夹的钝角。 |
| 3. | 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。 |
| 4. | The dot product of two vectors is defined as follows
两个矢量的点积定义如下： |
| 5. | Some properties of the dot product over the free module znm
上点积的若干性质 |
| 6. | Determines the dot product of two 4 - d vectors
确定两个四维向量的点积。 |
| 7. | Determines the dot product of the two specified 3 - d vectors
确定两个指定的三维向量的点积。 |
| 8. | Returns the dot product of two quaternions
返回两个四元数的点积。 |
| 9. | The dot product of the specified vectors
指定的向量的点积。 |
| 10. | The dot product of the two quaternions
两个四元数的点积。 |
