Ok, I understand that the dot product of vectors is the sum of the products of their corresponding elements, and that the dot product equals to the magnitude of the vectors time the cosine of the angle between them. What I do not understand is... what is the significance of dot product? how is it useful? what exactly does it symbolize? why the sum of the products of the elements?
please explain as simply as possible (i am in high school pre calc)... thanks...
