Ask the Professor Forum

Hello professor, I am having difficulties answering questions 9, 10, & 11 from the homework. I missed one class the first Friday after classes started so must likely you talked about it then. I apologize and thank for your help.

Hi Azariel,

These questions have a written solution at the end of section 7.2. I don't know if I can add much to those given explanations. Since these problems are based on theory alone, you might want to watch the videos below to see if they makes those written explanations clearer.

This will help with question 11.
