You can get plenty of help here. Just present your work as best you can and then we can engage in a directed give and take in which we look over your work, identify errors, omissions, and misconceptions and then we help you correct those. Depending on the situation and the person responding, it might be with a simple correct, a link to another site or post that might be useful, or a set of leading questions that is intended to walk you toward the right path. I tend to favor the latter most of the time.I really appreciate those who really tried to help me out with the problem. And i think i do get some more than from my instructor. The problem is from our second test which everyone did badly. This is why our instructor told us to do it again over the weekend. I tried to get my TA at college but he was out of town. And the materials covered in our class did not help at all. This is why i want to get help from internet. Oh well. Thanks again. I think i just do my best to work on it and hopefully it wil be fine.
So, to start things off, try explaining what this machine is supposed to do. Imagine you are trying to describe it to a student that is a year behind you.
