Re: Vector Cross and Dot ProductThere are two ways to explain this. Either geometrically or algebraically. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #5 20060323 10:19:47
Re: Vector Cross and Dot Producteh... if anyone is interested in the solution, here it is: #6 20060323 14:50:17
Re: Vector Cross and Dot ProductThat's a very strange diagram. The equalities you wrote down are definitely true for the case where all three vectors are in the same plane as you said, but just to make sure you understand, these forumulas are also true for any three vectors.
