# Deribatu taula

Kalkulu diferentzialean egiten den eragiketarik ohikoenetarikoa da funtzio baten deribatua aurkitzea. Taula honen laguntzaz esker edozein funtzio elementalen deribatua kalkula daiteke. Esan beharra dago, taulako f eta g funtzioak deribagarriak eta c zenbaki errealak direla suposatuko dela.

## Funtzio orokorren deribaziorako arauak
### Diferentzialaren linealtasuna

    $\left({cf}\right)'=cf'$
    $\left({f+g}\right)'=f'+g'$
    $\left({f-g}\right)'=f'-g'$

### Biderkaduraren deribatua

    $\left({fg}\right)'=f'g+fg'$

### Zatiduraren deribatua

    $\left({f \over g}\right)'={f'g-fg' \over g^{2}},\qquad g\neq 0$

### Funtzio potentzialaren deribatua

    $(f^{g})'=\left(e^{g\ln f}\right)'=f^{g}\left(f'{g \over f}+g'\ln f\right),\qquad f>0$

### Funtzio konposatuaren edo katearen erregela

    $(f\circ g)'=(f'\circ g)g'$

### Logaritmoaren deribatua

    $f'=(\ln f)'f,\qquad f>0$
