Consider the following family of equations:
sin(nx) = sin((n + 1)x), n = 1, 2, 3, . . . .
From the case when n = 1, 2, . . . , 10, can you guess how many
solutions are there to the equation
sin(1101x) = sin(1102x)
on the interval [−pi, pi]?

Since I was in high school I remember many discussions and arguments about 5.5 and 3.2 beer. I am originally from Kansas (USA) and with it being a dry state they provide 3.2% beer in Gas Stations and Grocery Stores and at liquor stores they provide 5.5% beer. As youngins high schoolers would make jokes that you got drunk off that lame 3.2% beer. However, I remember a more scientific discussion with a friend that difference is a measurement by VOLUME and WEIGHT. The 5.5% measurement is by volume and the 3.2% measurement is by weight. So, if that is the case, what is the difference in alcohol content between the two beers. Is one a supreme lightweight if he were to get drunk off of 3.2% beer or is he actually getting drunk because the alcohol available in both beers is similar? I would prefer people with a scientific / chemistry back ground to answer but if you know the answer or have any helpful input, by all means answer.

Thanks everyone!
