On the Nonmonotonicity of (Im(zn))

Research output: Contribution to journalArticlepeer-review


We show that the sequence (Im(zn)) is never monotone when z is a non-real complex number, and (Re(zn)) is never monotone, unless z=reiπθ, where θ=k/m for some odd m, and r is sufficiently large or sufficiently small. Similar results hold for the length of the projection of zn onto any line through the origin.
