Question

Solve |z| > (1/2)

Answer 1

Answer:

{$z|z$}U{$z|z>\frac{1}{2}$}

Step-by-step explanation:

Given the inequality $|z| > \frac{1}{2}$ you need to set up two posibilities:

FIRST POSIBILITY : $z>\frac{1}{2}$

SECOND POSIBILTY: $z$

Therefore, you got that:

$z\frac{1}{2}$

Knowing this, you can write the solution obtained in Set notation. This is:

Solution: {$z|z$}U{$z|z>\frac{1}{2}$}
