Se la potenciga funkcio estas konsiderata kiel funkcio de ''a'', ĝia inverso estas la ''x''-a radiko. Oni notas la logaritman funkcion de ''y'' je bazo ''a'' per la simbolo "'''log<sub>''a''</sub>''' ''y''" = ''x''; ĝi estas diinita por ĉiuj pozitivaj variabloj (''y'' ĉitie). La logaritmaj funkcioj je diversaj bazoj ''a'' kaj ''b'' diferencas je konstanta faktoro, kiu egalas al log<sub>''a''</sub>''b'' = 1/log<sub>''b''</sub>''a''; ekzemple: <center>log<sub>''a''</sub>''x'' = (1/log<sub>''b''</sub>''a''). log<sub>''b''</sub>''x''</center> La '''natura logaritmo''' estas la logaritmo kun bazo [[e (matematiko)|''e'']], skribita kiel "'''ln''' ''y''". La natura logaritmo estas la [[inversa funkcio]] (alinomita ''reciproka funkcio'') de [[eksponenta funkcio]], t.e. ''x'' = ln(''e''<sup>''x''</sup>) kaj ''x'' = ''e''<sup>ln(''x'')</sup>. La '''dekuma logaritmo''' (aŭ '''dekbaza logaritmo''') estas la logaritmo kun bazo ''10'', skribita kiel "'''lg''' ''y''". Ĝi estas la plej komune uzata. La '''duuma logaritmo''' (aŭ '''dubaza logaritmo''') estas la logaritmo kun bazo ''2'', skribita kiel "'''log<sub><small>2</small></sub>''' ''y''". Ĝi estas uzata pri la [[muziko|muzikaj]] [[gamo|skaloj]]. </textarea><div class="templatesUsed"></div><p id="mw-returnto">Reiri al <a href="/wiki/Logaritmo" title="Logaritmo">Logaritmo</a>.</p> <noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Elŝutita el "<a dir="ltr" href="https://eo.wikipedia.org/wiki/Logaritmo">https://eo.wikipedia.org/wiki/Logaritmo</a>"</div></div> <div id="catlinks" class="catlinks catlinks-allhidden" data-mw="interface"></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> </ul> <ul id="footer-places"> <li id="footer-places-privacy"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Privacy_policy">Regularo pri respekto de la privateco</a></li> <li id="footer-places-about"><a href="/wiki/Vikipedio:Enkonduko">Pri Vikipedio</a></li> <li id="footer-places-disclaimers"><a href="/wiki/Vikipedio:Malgarantio">Malgarantioj</a></li> <li id="footer-places-wm-codeofconduct"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Universal_Code_of_Conduct">Code of Conduct</a></li> <li id="footer-places-developers"><a href="https://developer.wikimedia.org">Programistoj</a></li> <li id="footer-places-statslink"><a href="https://stats.wikimedia.org/#/eo.wikipedia.org">Statistikoj</a></li> <li id="footer-places-cookiestatement"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Cookie_statement">Deklaro pri kuketoj</a></li> <li id="footer-places-mobileview"><a href="//eo.m.wikipedia.org/w/index.php?title=Logaritmo&action=edit&section=1&mobileaction=toggle_view_mobile" class="noprint stopMobileRedirectToggle">Poŝtelefona vido</a></li> </ul> <ul id="footer-icons" class="noprint"> <li id="footer-copyrightico"><a href="https://wikimediafoundation.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/static/images/footer/wikimedia-button.svg" width="84" height="29" alt="Wikimedia Foundation" loading="lazy"></a></li> <li id="footer-poweredbyico"><a href="https://www.mediawiki.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/w/resources/assets/poweredby_mediawiki.svg" alt="Powered by MediaWiki" width="88" height="31" loading="lazy"></a></li> </ul> </footer> </div> </div> </div> <div class="vector-settings" id="p-dock-bottom"> <ul></ul> </div><script>(RLQ=window.RLQ||[]).push(function(){mw.config.set({"wgHostname":"mw-web.codfw.main-6bcf67d78c-tjwp9","wgBackendResponseTime":158,"wgPageParseReport":{"limitreport":{"cputime":"0.004","walltime":"0.008","ppvisitednodes":{"value":17,"limit":1000000},"postexpandincludesize":{"value":713,"limit":2097152},"templateargumentsize":{"value":0,"limit":2097152},"expansiondepth":{"value":2,"limit":100},"expensivefunctioncount":{"value":0,"limit":500},"unstrip-depth":{"value":0,"limit":20},"unstrip-size":{"value":0,"limit":5000000},"entityaccesscount":{"value":0,"limit":400},"timingprofile":["100.00% 0.000 1 -total"]},"cachereport":{"origin":"mw-web.codfw.main-6bcf67d78c-tjwp9","timestamp":"20241127222617","ttl":2592000,"transientcontent":false}}});});</script> </body> </html>
