Camau gan Ddefnyddio Rheol Deilliadol ar gyfer Swm

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

$$3\times 8K^{3-1}+2\left(-32\right)K^{2-1}-88K^{1-1}$$

Lluoswch 3 â 8.

$$24K^{3-1}+2\left(-32\right)K^{2-1}-88K^{1-1}$$

Tynnu 1 o 3.

$$24K^{2}+2\left(-32\right)K^{2-1}-88K^{1-1}$$

Lluoswch 2 â -32.

$$24K^{2}-64K^{2-1}-88K^{1-1}$$

Tynnu 1 o 2.

$$24K^{2}-64K^{1}-88K^{1-1}$$

Tynnu 1 o 1.

$$24K^{2}-64K^{1}-88K^{0}$$

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

$$24K^{2}-64K-88K^{0}$$

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

$$24K^{2}-64K-88$$
