Before we can analyze rigid bodies, we need to learn a little trick to help us with the cross product called the ‘right-hand rule’. We use the right-hand rule when we have two of the axes and need to find the direction of the third. This is called a right-orthogonal system. The ‘ orthogonal’ part means that the ...In particular, the constant multiple rule, the sum and difference rules, the product rule, and the chain rule all extend to vector-valued functions. However, in the case of the product rule, there are actually three extensions: for a real-valued function multiplied by a vector-valued function, for the dot product of two vector-valued functions, andThese are the magnitudes of a → and b → , so the dot product takes into account how long vectors are. The final factor is cos ( θ) , where θ is the angle between a → and b → . This tells us the dot product has to do with direction. Specifically, when θ = 0 , the two vectors point in exactly the same direction.14.4 The Cross Product. Another useful operation: Given two vectors, find a third (non-zero!) vector perpendicular to the first two. There are of course an infinite number of such vectors of different lengths. Nevertheless, let us find …
