Homework Discussion for MA 35100 Kummini
You are encouraged to discuss homework problems (and other problems from the book, or from anywhere else) on this page. You may post hints, but not entire solutions.When you turn in your assignment, you should write the solution yourself.
Hey everyone, in order to keep this place from becoming a slur of random problems from the homework, I went ahead and organized hw help by problem set due date. If you have a problem you need help with and there isn't a page yet made for this week, just click "Create a Child Page" link to the left. Follow format: HW Mo Day MA351Spr10 without spaces. Example: HWFeb19Ma351Spr10 We use this long format because otherwise we might create a page with a name that already exists, which is not a good thing. Then just come back here after you post your problem and add to the bullet list so we can find you. Also, I will try to keep this up to date. Josh Hunsberger
Homework Discussion by Date
Would anyone be interested in forming a hw study group? Kswei
I think that's a good idea, especially during the week or two leading up to an exam. Mills7 21:53, 23 January 2010 (UTC)
What does the exam cover? Sohnw
Pretty sure he said the exam covers just chapters 1 and 2. Josh Hunsberger
For homework due on the 26th, I'm running into problems determining why sets of vectors might be independent or not. I don't understand the correlation. The book is somewhat vague. Anyone got any ideas in layman's terms? (3.2) Jefferst
Yeah I start the homework and was running into the same problem anyone got ideas?Jskelto
I haven't started the HW yet, so I'm not exactly sure what the problems are asking, but I can tell you how to figure out if vectors are independent. Vectors are independent if they aren't dependent. And they are dependent if you can multiply them by scalar constants and then add them up to zero. I'm not sure why they're called "independent" other than it might be because none of the vectors can be written as linear sums of the other vectors, and therefore do not "depend" on the other vectors. An easy way of testing whether vectors are independent is to simply arrange them in a matrix and take the determinant. Non-zero means independent. I'm copying this discussion into the Feb 26 link above. You should check it out. :) Josh Hunsberger
