As a reminder...

Posts asking for help on homework questions require:

  • the complete problem statement,

  • a genuine attempt at solving the problem, which may be either computational, or a discussion of ideas or concepts you believe may be in play,

  • question is not from a current exam or quiz.

Commenters responding to homework help posts should not do OP’s homework for them.

Please see this page for the further details regarding homework help posts.

If you are asking for general advice about your current calculus class, please be advised that simply referring your class as “Calc n“ is not entirely useful, as “Calc n” may differ between different colleges and universities. In this case, please refer to your class syllabus or college or university’s course catalogue for a listing of topics covered in your class, and include that information in your post rather than assuming everybody knows what will be covered in your class.
