Camau gan Ddefnyddio Rheol Deilliadol ar gyfer Swm

Cyfuno 6s^{2} a 5s^{2} i gael 11s^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}s}(11s^{2}-4s+8-6s)$$

Cyfuno -4s a -6s i gael -10s.

$$\frac{\mathrm{d}}{\mathrm{d}s}(11s^{2}-10s+8)$$

Deilliad polynomaial yw swm deilliadau ei dermau. Deilliad term cyson yw 0. Y deilliad o ax^{n} yw nax^{n-1}.

$$2\times 11s^{2-1}-10s^{1-1}$$

Lluoswch 2 â 11.

$$22s^{2-1}-10s^{1-1}$$

Tynnu 1 o 2.

$$22s^{1}-10s^{1-1}$$

Tynnu 1 o 1.

$$22s^{1}-10s^{0}$$

Ar gyfer unrhyw derm t, t^{1}=t.

$$22s-10s^{0}$$

Ar gyfer unrhyw derm t ac eithrio 0, t^{0}=1.

$$22s-10$$
