calculating angle
hello having position of 3 point i want to calculate the angle between them
If in 2D only, plot the 3 points on the same rectangular axes, so that you'd know how to get the angle between the two rays. For simplicity, put the corner of the angle on the origin (0,0). Use the
slopes of the rays. The slop... | {"url":"http://mathhelpforum.com/calculus/17602-calculating-angle-print.html","timestamp":"2014-04-16T20:20:53Z","content_type":null,"content_length":"10707","record_id":"<urn:uuid:96faa8a7-e400-47c2-8435-568c2b98e635>","cc-path":"CC-MAIN-2014-15/segments/1397609524644.38/warc/CC-MAIN-20140416005204-00219-ip-10-147-4-3... |

Little problem of divisibility
up vote 0 down vote favorite
Suppose we have $D$ prime and $d$ square free. Is there a way to express the smallest integer $n$ that makes $d \vert (Dn-2)$? If such an $n$ exists for a given $D$, $d$ it must exist less than $d$,
but is there some function of $D$ and $d$ that gives it expl... | {"url":"http://mathoverflow.net/questions/72258/little-problem-of-divisibility","timestamp":"2014-04-19T18:09:11Z","content_type":null,"content_length":"59950","record_id":"<urn:uuid:a69b8e86-67f9-46ff-8961-40dcb053dd8a>","cc-path":"CC-MAIN-2014-15/segments/1397609537308.32/warc/CC-MAIN-20140416005217-00564-ip-10-147-4... |
