Not interesting? I know more than a few people here enjoy mathematical discussions. Vector transformations to other coordinates is a useful skill toi have, and having an actual question about it is a nice change of pace.
Makes me wonder whether entering technical/hard sciences is a good idea after all .__.
Well, it depends on your outlook. It is a mentally satisfying experience, and can change how you view things. Especially if you decide to enter graduate school and focus on a specific area of study. The world seems so much smaller and yet so much more complicated.
