Os yw F yn gyfansoddiad dwy ffwythiant y mae modd eu gwahaniaethu f\left(u\right) a u=g\left(x\right), hynny yw, os yw F\left(x\right)=f\left(g\left(x\right)\right), yna deilliad F yw deilliad o f mewn cysylltiad â u wedi’i luosi â deilliad g mewn cysylltiad â x, hynny yw\frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right).
