Fall 2005 Comments - Week of September 5


Are we supposed to submit our prequiz via webwork? when is the due date of the prequiz?

The prequiz does not have to be turned in. It is for your benefit only. Student1919

How much time do we have to complete the quizzes?

About 15-20 minutes. Student1594

I think it would be helpful if the quizzes had answers posted in a seperate document.

If you would like the answers, you can visit a TA at office hours or send an email to a TA and they would be glad to help you. Student1594

On the course syllabus only 2 exams are posted for the months of Sept. and Oct. Does this mean that there won't be any exams on November? When is the final exam?
Yup. You only have 2 midterms. The final exam is 2 weeks after thanksgiving break (yours for this class i think will either be on dec 6 or dec 8). REMOVED oscar for a complete list of finals schedules. Student1919

Can on of the TA help me with the prequiz Answers. I am stuck on the back page and want to check my answers. My sn is GTBALL7 and email is gtg075h@mail.gatech.edu. I will be online all night. Thank you for you help. I could not make any of the TA office hours due to a 4 hour lab, classes, and baseball practice.

Why can't i open the prequiz anyREMOVED? Christan Money

You should be able to. It's still there. Student1594

so... if a function takes a color value and subtracts a ceartain amount and then restets that value to the new number...what happens when it goes negative? does it just rollback from 255 then? i.e- red=10 and the function subtracts 50 (seem familiar to anyone??:)) would the new value for red be 215 or 0??
It rolls around. once the pixel hits a value of 0, the next value is 255. The way you would know how to find what the value is, is if you started at red=10, add 256 to the value (red now equals 266), NOW subtract your 50. Your new value for the pixel is actually 216. Do you understand? For REMOVED explanation, see a TA at office hours :D Student1919

my JES program when it opens is just gray...how can I fix this?


It is difficult to tell you how to fix it without seeing what it is doing. Try visiting a TA at office hours (preferably with the computer if possible) and they should be REMOVED able to help you. Student1594
