General Announcements

General announcements will be placed here (by the instructor). Note that the discussion below should not involve specific questions and answers about homework problems.

Homework: For it to count, it must be turned in at the beginning of the class on the date it is due.

Some people have been having trouble finding the TAs during the office hours. Check carefully, they say they are there. Often they have a sign saying "CS 1050". In case you don't recognize them, here are photos: Wooyoung, Arwa, Hyuk

Quiz 2 and the key are now posted.

NOTE! The date for Quiz 3 has been changed!

Practice Quiz 3 (with answers) now posted. CORRECTED.

HW 9 key is now posted.

CS 1050 B

I doubt this will get answered before we get our final grades, but will our grades be curved at all?

Is f(subscripted A intersection B) (x) = f(A intersection B), or do they have different meanings?

These have different meanings. Check the notes. The former maps to {0,1}.

How do you convert a statement like "A has one movie in common with B's movie collection" to a relation?

So you have just one element in A intersection B.

CS1050 C

Is the proof for F-inverse of a function (problem #5) similar to the proof for F of the same function (problem #4) (as far as technique is concerned)?

A similar proof structure can be used. Start with an arbitrary element.

On HW5 #4, can we assume that f is 1-to-1?

No, you cannot assume this in #4.

General Discussion

Are the grades up yet?

Any word on when the Quiz 3 practice exam will be posted?

Posted. Slide 8 was incorrect but has now been corrected.

What building are the TA's in? I'm not familiar with the CCB.

TAs are on the main floor of CCB (the CoC building) in the commons area. Just make a left after you enter the main door.

Could the TAs please check the swiki more often on the nights before homework are do? I post questions and don't receive answers so I end up taking it down (and yes I leave it there for ample time to be answered). This would be much appreciated.

Sure..Sorry about that. Arwa

Since our exam is scheduled for the last period on Friday is there anyway we can have an earlier exam time scheduled? I know we had our exam for CS last semester at 6 on Tuesday night so we didn't have to stay until Friday.

I checked with the class, and there is little support for this. The exam will be at the scheduled time.
Actually having the exam, before Friday of exam week, would be nice now that I think about it. Is it possible to have it on Friday morning of dead week during the normal class period of 1050b? (of course extened to normal final period length, if necessary, if it is not conflicting with your teaching schedule)
