**1. The problem statement, all variables and given/known data**

Find the value of z when sec(z) = 3i.

**2. Relevant equations**

sec (z) = 1/cos(z)

**3. The attempt at a solution**

I assume that I need to transform into polar coordinates and then use some transformations. I'm really at a loss. If not a solution maybe a few hints to go in the right direction?

Thanks in advance.
