C2_W2 subtitle errata

I noticed some mistranscriptions in the transcript (subtitles, captions) for the course videos. Below is the errata for the 2nd week. I’ll post the errata for the other weeks in those groups.

The format for the errata is as follows. The approximate time is in braces, then the mistranscribed word or phrase follows, followed by a hyphen, then followed by the correct word or phrase. Like this:

[time] mistranscribed word or phrase - correct word or phrase

video 2
[0:36] red parable - red parabola

video 3 - partial derivatives part 2
the word “derivative” is misspelled as “derivate” on a slide (0:24)
[1:17] content - constant

video 5 - Gradients and maxima/minima
[0:19] parable - parabola

video 12 - optimization using gradient descent in 2 variables part 1
[0:42] for directions - 4 directions

video 14 - optimization using gradient descent - least squares
[0:17] grading - gradient
[0:33] palm - problem

video 15 - optimization using gradient descent - least squares with multiple observations
[4:02] So we divide it by m - So we divide it by n
[4:51] light - line
