0. MHF does not knowingly help with questions that count towards a student's final grade, which these most likely do. Such work is meant to be the work of the student, not the work of other people.
1. These questions are not calculus questions and should not be titled as such. Calculus questions involve differentiation, integration etc. The source of the question is irrelevant, the content iof the question is what determines the forum most appropriate for it. These questions are PRE-calculus in content.
2. Please don't post more than two questions in a thread. Otherwise the thread can get convoluted and difficult to follow. It is better for forum organization and better for you to get your questions answered in a more timely manner if you start new threads as necessary for remaining questions. eg. If you have five questions, post two of them in two threads and start a new thread for the remaining one etc.
And if the question has more than two parts to it, it is best to post only that question and its parts in the thread and start a new thread for other questions.
3. And when you do the above, please give a new name to a new thread. Don't use the same name as an old one.
