Central Differencing MATLAB question

I just can't solve the question guys, I've been sitting here and trying but nothing... I'm a beginner and this is the first semester using matlab.

The teacher also requires a small discussion of the answer and how i got the answer.

please help!

You would be more successful here, if you tried to solve your problem yourself - regardless of the fact that you may be stuck somewhere. At that point, people can help you with the problem at hand (for free!) rather than you paying them to do the entire assignment.

[Walter Roberson]

Note: K D did not ask for the assignment to be done for them: K D offered to pay for "help". That "help" could potentially include going over the problem, ensuring the physics is understood, working to find the current mental block, criticizing pseudo-code that K D writes, and helping K D when K D is stuck translating pseudo-code into MATLAB constructs.

$5 help here: http://fiverr.com/gigs/search?utf8=%E2%9C%93&query=matlab&order=&x=25&y=13. You may get great help, but it may be "you get what you pay for", so buyer beware.
