Harrysin, I teach college students and teach a course in which I use a great deal of math, including calculus. I retain the calculus from roughly 4 decades ago that I need in order to teach my subject. There is absolutey no way I could pass a calculus exam today. If I were serious about it I could probably start today and be able to pass rigorous calculus exam at the end of the summer.
The problem that started this thread does not require calculus; it does require trigonemetry. Again, if I had the summer, I could probably pass a rigorous exam by the end of the summer.
As for the answer to the original question, give me some more time. My year just ended and I am still brain-dead exhausted. (I do not even trust myself to get out my router yet!)
