Subject: [lojban-beginners] naming the phrase "root of unity"

In mathematical terminology, there is a phrase "root of unity."

per wikipedia, a unity root is a special case of a complex number.

per jbovlaste, complex number is {lujna'u} i.e. {pluja namcu}, a complicated type of number -- not pleasing to me, since it is more a two-dimensional number than one that is {pluja}.

(I note that "imaginary number" also has the numbingly literal jbovlaste definition of {xarna'u}. But it's easy to be a critic.)

For complex number, something based in {seplita} would make more sense. Except that x2 of plita is supposed to be a set, which makes it hard to talk about one point in the plane.

This is probably all meant to be sorted in mex, but still, a unity root is a complex number that when multiplied by itself, equals 1. {da binxo li pa le nu da sezpi'i} ... or something crudely like that... I wonder how many errors I made in that one sentence?
