oh well,grab this question..
(a)
Find the constant of the expansion until x^10 for (1+x)^5 (3-2x)^7
(b)
By using De Morgan's Law and other properties of set algebra,prove that
(A'nBnC) U {A' U (BnC')}' = (AnB') U (BnC)
U=Union
n=Intersection
' =Complement
haha..enjoy the questions..

Here is an optimisation problem I am currently working on.
Given an arbitrary straight line L of which the only thing that is known is that it is located at a distance of 1 unit from the origin O
Find the optimum strategy to go from O to L in the mimimum amount of time. For that strategy, find the average time needed and the worst case time.
You can think of it as a ship in the fog 1 mile from the coast but the incompetent captain doesn't know the direction of the coast.
The problem arrose in finance.

Actually, if you solve that one, could you tell me the solution? I'm tired of waiting for this damned quadratic sieve to finish (it's currently 14% done after 7 hours... sigh).
Edit: ah, found them. I'll give you a hint which should save you several hours of computer time: one of the factors is 4531530181816613234555190841. There are two others.
