a) modulus of Z-3i<3. Find the greatest possible value of modulus of z. Modulus means square bracket.
I have no idea about finding the greatest possible value.
The region of the complex plain such that is the interior of the circle ofOriginally Posted by kingkaisai2
radius centred at . If the region was in fact closed (that is )
then would give the maximum modulus of , but the region is open,
so there is no with maximum modulus in the region.

Let,
Then,
But,
Thus,
Square,
This is a circle center at
Now look upon CaptainBlank's post.
He said that is the region is closed meaning,
then you can find a maximum value, namely, 9. Which would give 6.
If the region is open meaning,
then you cannot find a maximum value.
