/sci/, calculus 3 (vector calculus) is boring as shit. I feel like I'm just computing arbitrary shit that I can find from vectors or planes. Because the material is so mind numbingly boring, I'm having trouble focusing. I thought that calc I and II were really interesting, and I enjoyed those classes.

Does it get better? Does anyone else feel this way?

OK /sci/, I've been pondering this puzzle for weeks and I can't think of the solution.

In front of you there is a turntable. On the turntable are 4 identical cups, situated in each of the cardinal directions (N,E,S,W). Under each cup is a coin that is either facing either heads or tails. The initial states of the coins are random. Your goal is to get all the coins facing the same direction. To do this, you choose 2 of the cups and simultaneously pick them up. You then have the choice of flipping neither, one, or both of the coins under the cups. After you replace the cups, you are blindfolded and the turntable is spun so you don't know which cup is which. You can repeat this process until all the coins are facing the same direction. To win, you don't need to know if all the coins are facing the same direction; there's some omniscient dude who tells you when they are.

Apparently, with the right strategy, there's a finite maximum number of moves before you are guaranteed to win. Can anyone figure out the strategy?
