Unreliable complex calculation in CAS? Bug?

I think the problem is that the polar input in CAS doesn't give results in exact form... not much you can do abt that, maybe it's a bug. Wouldn't be hard to write your own routine for that in PPL though.

If you input all the phasors in exact form (cos(x)+i*sin(x) or complex exponential) the CAS gives the correct exact result vector:

[[1443*√3/100],[-1443*√3/100],[0]]
