Oh, that's great!

Those sections are yours, thank you

Section 3:

12:47 - "the notation, F(x, y, z)" - I hear "Capital F, x, y, z". Should it be "Capital F of x, y, z"? Or maybe "Capital F, with x, y, z in parentheses, voiced as F of x, y, z"? That way it can be visualized but then read in the regular way later on (as they are).

16:16 - another case of maybe reading it to describe it rather than reading it the way it should be read (err, something like that). I think it should be "d superscript 2, y over d, x superscript 2". Otherwise just listening to it, one would think you're describing d2x/dx^2

What do you think?

Depends on context. When it was known that we were talking about the second derivative, I remember lecturers saying "dee two y by d x squared". Wouldn't "superscript two" imply something else entirely from what we are talking about?

Of course, we are referring to a thirty-odd year old memory, so I wouldn't swear to it.

In the recording I'm in the middle of doing, I've said "dee two sine theta by dee theta squared equals negative sine theta".

P.S. All this talk of university level science has brought back a memory of an old prof of mine who used to say (with his pronounced German accent): "Zer purpose of zer yooniversity professor iz to take zer student to zer edge of zer abyss of zer unknown ... und throw him over!"

SOTE, I know why I suggested what I did in my PL notes.

Yes, I know that the correct rendering is as spoken. You missed my point. Clear your mind of all prior calculus knowledge. If you heard someone say, "dee two y by d x squared", how would you write it out? Probably like this:

d2y
---
dx^2 ("^2" being the superscripted 2 indicating "squared").

The context of the section 3 text is that it is telling the reader how to say the notations. It shows the correct notation, then says, "which is said, 'dee two wye by dee ex squared, or dee two wye over dee ex squared'". I think the notation should be vocalized more clearly so that the reader knows what is on the written page vs. how it is supposed to be pronounced, since the text indicates in the very next phrase how it is supposed to be pronounced.

The BC and reader can determine what is best in this case.

Fair enough. Would the immediately following explanation of the correct pronunciation in Section 3 mean that all subsequent sections were free to deliver it in the received manner?

This is getting a bit like a wiring diagram, isn't it?

I think so, but I'm only the DPL. I'm not the BC nor MC.

OK, ta, Tricia. I'll proceed on that assumption, but will stayed tuned for updates.

so, change to:

12:47 - "Capital F of x, y, z"? and 16:16 - "d superscript 2, y over d, x superscript 2"

?

That's what I think. What do you think? I'd also like the input of our intrepid BC.

Sorry I've taken a few days to respond. If I've missed anything let me know. Thanks everybody!

I think that will make the most sense, please do do that. Thank you!

Thank you for your file! It's in the MW.

Yes, I think that will work best.

Thanks!

Section 33:

4:23 - page 165, the second equation after the "Therefore" - I hear "cosine(pi/theta - theta)" text is "cosine(pi/2 - theta)"

No matter how much I try to recapture whatever the tone or timbre of the original recording was, my spot edits always wind up sounding positively ... sepulchral. Who knew Bela Lugosi was the patron of the editing process?

Thanks,
SOTE

It goes by so quickly in this case, I doubt anyone will notice.

PL OK.
