Thank you for using the site. I'll be happy to help you if I can.
Do you have the problem information, or a link to the previously answered question that you are referring to?
Thanks. I'll take a look at this and see if I have a solution available on my files.
I don't seem to have a solution for this problem in my files.
Also, I've never heard of the "auxiliary variable cells method", nor can I find any information about it online. I have a suspicion that this term is something that your instructor may have invented, which may be known by another name elsewhere. Do you have an example problem from either your course material or textbook that would demonstrate the particular process that you are expected to follow?
