Ah. I think he already ask question. Maybe you missed it so I will point out to you.
Anybody good at trig here, I mean really good?
There! Can you see he asked his question?
As that isn't a question of Trigonometry, it is a question of ability to solve a trigonometric equation.
And THAT is the question he did NOT ask in a fully formed manner such that anyone; even if they are only mediocre at Trigonometry might be able to provide an answer. That is should he actually post the actual mathematical equation, or challenge he needs a solution, or the proper direction to achieve a solution to.
As it could be that any of us could rise to the challenge and provide said direction, or answer when and or if it is actually posted for our consideration.
