Funktion $$$\frac{\ln\left(x\right)}{\ln\left(2\right)}$$$ derivaatta
Aiheeseen liittyvät laskurit: Logaritmisen derivoinnin laskin, Vaiheittainen implisiittisen derivoinnin laskin
Syötteesi
Määritä $$$\frac{d}{dx} \left(\frac{\ln\left(x\right)}{\ln\left(2\right)}\right)$$$.
Ratkaisu
Sovella vakion kerroinsääntöä $$$\frac{d}{dx} \left(c f{\left(x \right)}\right) = c \frac{d}{dx} \left(f{\left(x \right)}\right)$$$ käyttäen $$$c = \frac{1}{\ln\left(2\right)}$$$ ja $$$f{\left(x \right)} = \ln\left(x\right)$$$:
$${\color{red}\left(\frac{d}{dx} \left(\frac{\ln\left(x\right)}{\ln\left(2\right)}\right)\right)} = {\color{red}\left(\frac{\frac{d}{dx} \left(\ln\left(x\right)\right)}{\ln\left(2\right)}\right)}$$Luonnollisen logaritmin derivaatta on $$$\frac{d}{dx} \left(\ln\left(x\right)\right) = \frac{1}{x}$$$:
$$\frac{{\color{red}\left(\frac{d}{dx} \left(\ln\left(x\right)\right)\right)}}{\ln\left(2\right)} = \frac{{\color{red}\left(\frac{1}{x}\right)}}{\ln\left(2\right)}$$Näin ollen, $$$\frac{d}{dx} \left(\frac{\ln\left(x\right)}{\ln\left(2\right)}\right) = \frac{1}{x \ln\left(2\right)}$$$.
Vastaus
$$$\frac{d}{dx} \left(\frac{\ln\left(x\right)}{\ln\left(2\right)}\right) = \frac{1}{x \ln\left(2\right)}$$$A
