[269] Adjoint, and IOU's from today

[Gautam Iyer]

Hi All,

Looks like they have now officially changed the name to "classical
adjoint" or adjunct / adjugate:

Regardless, the two missing calculations from today should take me about
20 minutes to do. Instead of burning half the class on it on Friday, I
will do them today at 3:30 pm on Zoom, and remind you about what the
"adjugate" is. (There's a slick way to do the calculations without
getting too dirty.)

If you want to watch it live, download and install Zoom, and join the
meeting with ID:

    4122688419

(You can also do this from your browser.) Please keep your mike muted if
you are not asking a question (clicking / turning pages causes lots of
feedback).

If you can't join live, the video will be posted on the class website
shortly, along with a PDF of everything I write.

Best,

Gautam

PS: Practice questions and an email about your final coming up shortly.
