Juhised jagatise tuletisereegli kasutamisel

Iga kahe diferentseeruva funktsiooni korral on kahe funktsiooni jagatise tuletis nimetaja korda lugeja tuletis miinus lugeja korda nimetaja tuletis, mis on seejärel jagatud nimetaja ruuduga.

$$\frac{\left(x^{2}-x^{1}-2\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{3}+1)-\left(x^{3}+1\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{2}-x^{1}-2)}{\left(x^{2}-x^{1}-2\right)^{2}}$$
