1.)You posted Sin(0+2n(pi)) = 0 and Sin((pi/2)+2n(pi)) = 1. Where did the 0 and the pi/2 come from? Are these just something that you have to memorize or use a calculator for, or is there a way to figure out what to add to 2n(pi) to get any number in a sin equation?

2.) It's obvious that "min" means "minimum," but why on earth put it there?

**Because the function is periodic and f(b)-f(a)=1 for ever-increasing angles**

3.) I noticed that your answer is (pi)/2, whereas mine is (pi)/(2w). How is it that, in your answer, the "w" is somehow irrelevant?

**No, I left the expression as a product, from there we can just divide both sides by w.**

I apolagize for my ignorance (hopefully you got a chuckle out of it), but it's been years since I had trigonometry and even the more basic stuff is barely still in my memory.

Again, thank you
