This is pretty much exactly what I was looking for. I do have one question, in the second block of code you set $\hat{\theta}$ using OverHat[\[Theta]] = Vector[{(-1/r) Sin[\[Theta]] + (1/r) Cos[\[Theta]]}, 2]. What are the (1/r)'s for, I would think that now the unit vector may not have a magnitude of 1. Is there a reason that has to be there for it all to work that I don't understand? | |
