Partial fraction expansion: repeated real poles UPDATED

Screencast for CHE 435 at NC State University in the Chemical and Biomolecular Engineering Department.

This is a re-upload of a screencast that originally contained an error. In the middle of the derivation, I had said and wrote "n-1' when I meant "1". I originally made a "youtube annotation" to fix it, but the annotations went away (plus, you can't see annotations when viewing a video on a mobile device). So I edited the video and re-uploaded it here. If you watch the video, you can probably tell where the edit was made :)
