Vectors in polar coordinates

[retoa]

Hello !

Is there a way to work with vectors in polar coordinates (respectively spherical or cylindrical for 3D) like you do with complex numbers?

In 2D you can write the vectors as polar complex numbers for sums, but you can not do dot multiplication between complex numbers, nor cross multiplication as you need a third dimension.

With my 48sx I could do it, is it possible on the prime too, or do I have to convert all vectors in rectangular and then reconvert the result in polar after calculation?
