Weighted Stats FAQ
Hello, pokefans! At this point you've no doubt noticed that this month's usage stats look a bit different. That's because, instead of just counting the number of times each Pokemon appears on a

Cannot find my own mistake (derivation)
So I have this:
$x^{y} = y^{x}$
which, in case $x$ and $y$ are positive, may be graphed like:
$x^{y} = y^{x} \Longrightarrow e^{y \cdot ln(x)} = e^{x \cdot ln(y)} \Longrightarrow y \cdot ln(x)... | {"url":"http://mathhelpforum.com/calculus/163968-cannot-find-my-own-mistake-derivation.html","timestamp":"2014-04-16T06:37:04Z","content_type":null,"content_length":"72487","record_id":"<urn:uuid:eb00798b-f4d6-487b-8756-a9dea895cc4a>","cc-path":"CC-MAIN-2014-15/segments/1397609521512.15/warc/CC-MAIN-20140416005201-0065... |
