So let’s take the function f and replot it here and remember this is f of theta equals theta cubed, and let’s again start off to some value of theta.
I am wondering:
From where are we remembering this? Did one of the videos get lost or was this one truncated?
I don’t know the real answer. It’s possible that the video has been edited. But it doesn’t really matter: just treat it as if he said “for purposes of this example, we are using this function”.
Totally, that’s what I did. Just wanted to let folks know in case that was accidental, that the lead in was accidentally lost.
