This is exactly the same as a normal golf course except that the holes have a sloped turn at the bottom. There is no way of telling, by just looking, whether or not the ball is in the hole. You get the rest. (Just write a score of 36 on your card to split the difference then go to the clubhouse for drinks.)-- AusCan531, May 31 2012 Easy. Just use: DSolve[{-(h^2/2 m) psi''[x] + V[x] psi[x] == E psi[x], psi[-Infinity] == 0, psi[Infinity] == 0}, psi[x], x]-- sqeaketh the wheel, May 31 2012 Electric field or magnetic field... or just a shotgun start?-- UnaBubba, May 31 2012 Hell [sqeaketh], even golf is easier than that.-- AusCan531, May 31 2012 random, halfbakery
