i can get the correct answer as shown in the book.
but i think i need a little bit more expaination on this.
Why the maximum of arg(z) is the double of the arg(u)?

Given that u=1+2i, and also the |z-u|=2.
Already sketch the locus of the complex number z such that|z-u|=2.
Now, question ask me to find the greatest value of arg z for points on this locus.
How can I get the answer?
Thx for helping ya.!:)
