Golf: 8 players over 4 days in 4-balls |
2012-05-03 |
|
JimB pose la question :
I cannot seem to get this to work. Previous answers cover 2-balls, but we are 4-balls.
What we really want is for each player to play with each other, at least once and no more than twice.
Ideally, each would also play equally in the first and the second 4-ball of the day.

The parameterization of a parabola |
2012-04-27 |
|
Shawna pose la question :
I am having problems finding the parameterization of a parabola. The question I was given is: Find the work done if a particle moves from the points (-2,4) to (1,1) along the parabola y=x^2, while subject to the vector force of F=(x^3y,x-y). So how would I start with finding the parameterization of a parabola?
