Prime tries to turn your VLL squared over the angle 30°/S3phi, and with S3phi bearing a power unit, that results in a unit error: The unit deg/W is not compatible with an angle. Now Prime isn't very careful with pointing to the right spot of an error, so you're getting a somewhat cryptic error message. Here's the same situation:

If you put brackets ( and ) around the polar conversion it works.

Or rewrite:

Which also indicates that you should be cautious with the other expressions involving that polar conversion operator:

Thanks!  That worked.
