Question: Determine whether the following relation is an equivalence relation. If so, determine its equivalence class: { (x,y) C C : |x| |y|

Determine whether the following relation is an equivalence relation. If so, determine its equivalence class:

{(x,y) ∈ C × C : |x| ≤ |y| ∨ Arg(y) ≤ Arg(x)} 

(C = the set of complex numbers. Recall: In the Euler form of a complex number x = re^(iφ), Arg(x) = φ)
