We have now created a "Homework Help" section on the forum. Please note the following :

1. We will attempt to assist with homework questions, but will not do anyone's homework for them
2. The OP will need to identify the origin of the problem, the type of class, and the level of maths involved
3. Some attempt at solving the problem must also be evident, and must be presented on the forum
4. No "ready made answers" are to be provided, just hints and suggestions how to go about solving the problem

Please do contact any member of the moderator team if you have further questions. I have incorporated these guidelines into the "Forum Rules" sticky as well.
