I'm trying to get familiar with the Physics package. It's huge. Since I know vector projection, I can guess what a projected vector might be. But what would a non-projected vector be in a physical context?
A web search for non-projected vectors was unsuccessful.
My best guess is that non-projected vectors in Maple are those where no coordinate system is specified for vectors in an expression for a physical law. Like here in Maxwell equations. Am I correct?
To distinguish between these vectors the Physics[Vector] package uses an underscore “_”.
If my understanding is correct so far, I have three questions:
- Can I replace the unit vectors of implemented projected vectors to something else (e.g. _i to e__x)
- Is it possible to define projected vectors beyond what is implemented in Maple?
- Can I use the packages VectorCalculus and Physics[Vector] at the same time?
