My 8th grade math teacher showed our class a simple formula that allowed you to use the dots on the side and top/bottom rails with the pockets. and with simple addition and subtraction allow you to put the cue anywhere on the table, providing you hit the ball strait and at the proper speed. This formula she showed us also didn't include any geomety angles and degrees in the caculations. so has anyone seen this also and could explain it to me one more time.

Yeah it is in Donald in Mathematic land. The balls hit at 45 degree angles and bounce off at 45 degrees, so the "interior" angle is 90 degrees. Now the sin of 90 degrees is 1. So if the formula involved this trig function, you wouldn't see it in the formula.

my 8th grade teacher showed me that too.
It was like a Donald Duck in Math land movie.
Im glad teachers teach the same thing all over the world, but nobody really learns anything.
