Solutions (?) for week 2 problem sessions
I thought you might want to know what I got if I worked out numerical answers to the questions asked in the two problem sessions for week 2. That is, not jut the plan, which is on the video, but the actual number answers. These values are posted under Hints & Kinks. Be sure to read the "important note" that follows. ,,rcb

Captions
There is some discussion in the forum about some missing captions this week. I thought you might like to know how captioning works, for Bioelectricity. The Duke team makes the videos, then transfers them to Coursera well in advance of their coming to you. Coursera adds captioning. Captioning in English is a specialized, professional business, and I have heard that Coursera employs such specialists to make the first round of captions.
Once English-language captioning is complete, there is a transcript. Translators re-write the captions into other languages. As a student you can select which language to see. If the language you need is not there, and if you or others are willing to volunteer, Coursera will work with you to make captions in other languages available (click on their web link).
I think the captions are a great asset to Coursera courses and, recognizing that those registered for Bioelectricity come from over 100 countries, I am sure that many of you rely and enjoy the captioning service. ..rcb
