In the third video lecture the professor says "Does anyone remember from last time what [sinx(cosdelatax - 1)]/deltax goes to?" Is there a video between the 2nd and 3rd that I am missing or is this explained in the notes or study assignment? I don't recall him covering that material in the video series.

Hmm he covers it later in the lecture.  Nevermind.
