Actually, your explanation (what there was of it) was commendably concise. And
you didn't throw in a lot of words like "sine function" at random.

But it was also incomplete, since you left out the two biggest reasons why tip
vortexes form in the first place. If you look back to see my answer to your
explanatory post, you'll see at least part of what you left out.



Well if you know the answer then post it. I'll be impressed if you can
correctly state the boundary conditions for vortex shedding.

Cheers
