If someone could help me with this one, I'm almost entirely lost as to what methods will work for this....

Prove for every positive integer n: 3 divides evenly into n^3 - n

I.e. 3 will divide evenly into n^3 - n with no remainder left.

My prof seemed to recommend induction, but I don't see how to do that here...and then I tried to do it by cases, but the first case i tried (when n is odd) won't seem to do me any good (it reduces to 8k^2(k+2)+2 ....how can i prove that's divisible by 3??)

Thanks in any case, I need the help!!

Okay, I am checking into a hotel for corporate training. We will be assigned roomates. Your roomate will be determined by when you check in. For example:
Male 1 is Male 2's roomate
Male 3 is Male 4's roomate
Female 1 is Female 2's Roomate
Male 33 is Male 34's roomate... and so on.

Is is true that:
a) There is a 50% chance that there will be an odd number of people and a 50% chance that there will be an even number of people?

b)If there is an odd number of people and the rooms definitely only accomodate 2 people, that there will be someone rooming by themself?

and most importantly

c) if I make sure that I check in AFTER everyone else, that assuming a and b are true, there is a 50 % chance that I get my own room (as long as I am the LAST person to check in)

The Question is: Find the tangent equation when x = 0 for y = [x+ (x+x^1/2)^1/2]^1/2. So, basically i just need to know how to find the derivative of this function with the chain rule so i can get the slope of the tangent line.

What is the value of the expression:
(1+1/2)(1+1/3)(1+1/4)...
(1+1/2004)(1+1/2005)

the dots just mean it has skipped the brackets in between.
calculators may not be used for this question.

Any help on how to solve this question? The answer is 2003 but I'd like to know how to work it out.

Here is the question...
There are two cars: an old truck and a fairly new car. The truck currently has 16 times as many miles on it as the car had when the truck had 3 times as many miles as the car has now. Between now and then, each vehicle has been driven the exact same number of miles. The truck has not yet been driven 100,000 miles. All mileage amounts are in thousands. How many miles has the car been driven now?
