How can I make something like dot products tangible? Are there real life examples where dot products are used? This is for motivating students. Aware that we can test for orthogonality. Thanks in advance for any replies. Really appreciate anyone taking time out to answer these questions.
Frankly I am puzzled by this kind of request.
As Mr F pointed out above, there is so very much available, it is pointless to 're event the wheel'. I see no point in replying to such nonsense questions.
