limit proof

limit proof
One way determine the deriveative of $e^x$ is to use inverse functions (natural logs). Another way is to use the definition of a derivative. Thus, $\frac{d}{dx}e^x=\lim_{h\rightarrow0}\frac{e^
{x+h}-e^x}{h}$.

Physics Forums - View Single Post - |X| is a random variable
Good, so X and |X| are random variables. Let me put it in this way:
1. If X is a random variable, then |X| is also a random variable too.
2. If |X| is a random variable, then X is a random variable too.
First case, we say that X and |X| are two different ran... | {"url":"http://www.physicsforums.com/showpost.php?p=941839&postcount=5","timestamp":"2014-04-16T13:54:41Z","content_type":null,"content_length":"7308","record_id":"<urn:uuid:cd73d0bd-a55a-4b4d-83e1-32b93192e063>","cc-path":"CC-MAIN-2014-15/segments/1398223205375.6/warc/CC-MAIN-20140423032005-00659-ip-10-147-4-33.ec2.in... |

Find the Cos(2alpha) when its in the 2nd quadrant
I know I need to set $cos(2\alpha)=1-2\sin^2(\alpha)$ which is then $\frac{31}{49}=1-2\sin^2(\alpha)$ which is then $2\sin^2(\alpha)=1-\frac{31}{49}$ now I think I get $2\sin^2(\alpha)... | {"url":"http://mathhelpforum.com/trigonometry/208320-find-cos-2alpha-when-its-2nd-quadrant.html","timestamp":"2014-04-18T19:23:02Z","content_type":null,"content_length":"87854","record_id":"<urn:uuid:4e51aeea-f278-42aa-9a87-7e4ac50c37e0>","cc-path":"CC-MAIN-2014-15/segments/1397609535095.7/warc/CC-MAIN-20140416005215-0... |
Why is a 2d TQFT formulated as a functor?
up vote 22 down vote favorite
Usual mathematical formulation of a 2d (closed) TQFT is as a functor from the category of 2-dim cobordisms between 1-dim manifolds to the category of vector spaces (satisfying various properties.)
For example, a pair of pants (a morphism from $S^1$... | {"url":"http://mathoverflow.net/questions/66699/why-is-a-2d-tqft-formulated-as-a-functor","timestamp":"2014-04-17T21:47:52Z","content_type":null,"content_length":"61784","record_id":"<urn:uuid:82ea8263-0bdd-4cc4-b91b-5b69927750d7>","cc-path":"CC-MAIN-2014-15/segments/1397609532128.44/warc/CC-MAIN-20140416005212-00443-i... |
