3.2 Q1?

(1/1)

Ende Jin:
There is no example in the book.
The only way I know is to translate it into multivariable calculus and use Lagrange multiplier. However, is there an easier way?

Ende Jin:
Never mind, I figured out that I can just specifically analyze.
In Q1, I just draw a graph to see that $|z+2|$ can be at most 3 while the numerator is always 1.
