1. The problem statement, all variables and given/known data Find the set of points z=x+iy from the complex plane which satisfy this conditions: a)Re(z)[itex]\leq[/itex]0 b)|z|=3 2. Relevant equations 3. The attempt at a solution I've solved the first one... Re(z)=x so x[itex]\leq[/itex]0 x[itex]\in[/itex](-infinity,0] But for the second one? Should I find x, y or should I find z?
