You have already asked the solution. What are you trying to do ? Make fun ?
total newbie's point is that this solution is done just as the one you asked before. Try to follow the same steps as were used in the previous solution. Remember that learning how to do it yourself is always the point of asking for help in math. This forum will not be available in a test situation. Good luck. Also feel free to post a solution here and we can check it for you.
