Apr25 asked Show that there is no rational number $r=m/n$ such that $r^3=3$ Apr25 accepted Proving a complex equality Apr25 comment Proving a complex equality So for the trivial case, you can't use the quotient you've set $z$ equal to? Apr23 comment Proving a complex equality I'm aware of that answer, but I'm looking for an algebraic answer simply because that wouldn't come to me immediately. How did you see that it was an ellipse? I ask because it's not in the familiar form that you see in conic sections of calculus.

Apr13 comment Finding a closed form expression for this sum @MarcvanLeeuwen How did you search for that? I didn't know how to search for it because there's no specific name or term associated with it. O.w. I'd just have to look through all the results one at a time.
