The players on the Dunkers basketball team must win at least twice as many games as they lose to make the playoffs. Graph the set of points (L,W) that satisfy these conditions.

I know that the inequality would be (W > or equal to 2L), and I also know that the graph would consist of discrete points because you cannot have a portion of a win or loss. However, I don't know what the set would be. Would it be infinite, and if so how would I graph that? Or, is there a certain number of games that are to be played, even though it doesn't specify?

Thanks for any help you can be.

I need to prove this series
(-1)^(n+1) * (n^2) / [(n^3)+4]
is convergent or divergent.
I did the intergral test for (n^2) / [(n^3)+4] and it diverged.
So then I took the limit as n goes to infinity for (n^2) / [(n^3)+4] and got zero.
I know this series decreases but I can't figure out how to prove it.
Please help.
Should I do:
An+1 - An < 0
(An+1)/An < 1
An' < 0

Lorentz transformation is
t= gamma(t' +(v/c^2)x')
x=gamma(x'+vt')
y=' and
z=z'.

i don't know how to show
ct=ct'cosh(theta) +x'sinh(theta)
x=ct'sinh(theta) +x'cosh(theta)

i'm really stuck to where to start

John has a constant velocity of 5ms-1 and Norma is going at (3i+4j)ms-1...show that they will collide..and at what time...

*how does one find the time (of collision possibly) in any position vectors question... ..?is there a specific equation...i think -position vector+initial r + (v*t) is right...but with the i and j's i get confused..:S

I made some calculations using MATLAB but I am not quite sure what the result

NaN -1.2838e+045i

means. Is it -1.2838^(45i) or something else?
