Problem 3b:
+
Alright I know that problem 1 is easy cause you just have to integrate out the y for fx(x) and integrate out the x for fy(y)...BUT integrating out the y is horrible.  i know its a uv - integral of vdu...but the original expression stays...so i subtracted it over to the other side and divided by the (1 + 1/(1+x) that remained.  Is that the right avenue to go? cause it seems crazy but mathematically I think it works -- Cory

Hint: If your derivatives look disgusting, convert to sins/cosines. That dirty sinc function might appear.

Hint2: If you're stuck, try L'Hopitals Rule.

What is q for the probability generating functions listed in the book?
