Homework Statement
-∏<arg(z)<∏ (z≠0)
Homework Equations
arg(z) is the angle from y=0
The Attempt at a Solution
Arg(z) spans the entire graph since -pi to pi is the full 360 degrees so I put:
-∏<arg(z)<∏ -->
0<arg(z)<2∏+k∏, (k ε Z) -->
arg(z) [itex]\subset[/itex] R -->
arg(z) = R: all real numbers
but I don't know if that describes the closure since last time when describing the closure it would be Cl(E)={zεC :-∏<arg(z)<∏}
Would what I did be showing the closure with formulas? Also it's an open set, so I thought it would be an interior as oppose to a closure.
