# Complex numbers watch

1. What exactly is a locus?

I have a question to find the locus on the complex plane(I'm pretty sure that the argand diagram), given by the inequality [MODULUS]Z + 3 + 2i[/MODULUS] >= 4

Thanks.
2. A locus is a line which usually has an area below it that is the required area. So draw the equality on the argand diagram and shade everything between the 2 lines.
3. What exactly do you mean by draw the equality?

Sorry I'm terrible at complex numbers. All I really know is i^2 = -1 and basic complex arithmetic.
4. A locus (meaning "place" - thank you wikipaedia) is just the set of points satisfying a given criteria.
