=b_i(S)-b_i(D)$ is... | {"url":"http://mathoverflow.net/questions/91599/how-to-compute-the-betti-numbers-of-s-d-for-a-surface-s-and-a-divisor-d","timestamp":"2014-04-18T03:17:02Z","content_type":null,"content_length":"50273","record_id":"<urn:uuid:6abb50af-b071-4662-9169-f44ff61cd083>","cc-path":"CC-MAIN-2014-15/segments/1398223205137.4/warc/... |
Matrix Exponentiation
Matrix Exponentiation is a useful technique that can be applied to a wide variety of problems. Most commonly it is used for efficiently solving linear recurrence problems and as such can be used in
any problem that can be represented as a linear recurrence. The main problem lies with the fact that... | {"url":"http://wilanw.blogspot.co.uk/2009/12/matrix-exponentiation.html","timestamp":"2014-04-20T13:19:21Z","content_type":null,"content_length":"74707","record_id":"<urn:uuid:fc85787c-4271-41b5-8c87-b81186ee8052>","cc-path":"CC-MAIN-2014-15/segments/1397609538787.31/warc/CC-MAIN-20140416005218-00404-ip-10-147-4-33.ec2... |

As a puzzle, commenter nobugz asks, "What kind of infinity is 1.#J?"
double z = 0;
printf("%.2f", 1/z);
Now, the division by zero results in IEEE positive infinity, would would normally be printed as 1#INF. But the catch here is that the print format says "Display at most two places after the... | {"url":"http://blogs.msdn.com/b/oldnewthing/archive/2013/02.aspx?PageIndex=1","timestamp":"2014-04-20T20:12:24Z","content_type":null,"content_length":"101874","record_id":"<urn:uuid:845f4c87-8b4f-479f-9061-872b2f1a598e>","cc-path":"CC-MAIN-2014-15/segments/1397609539066.13/warc/CC-MAIN-20140416005219-00641-ip-10-147-4-... |

Advance Functions. Must See!
Explain what happens to the graph of the function f(x) = logbx when b is equal to 1.
If g(x) = bx and h(x) = logbx, would the graphs of these functions intersect if b = 1? If so, at what ordered pair?
