Yig'indi uchun derivativ qoidasidan foydalanish qadamlari

Polinomialning hosilasi bu uning shartlari hosilasining yig‘indisiga teng. Konstant shartning hosilasi 0. ax^{n} ning hosilasi nax^{n-1}.

$$2\times 9a^{2-1}+\left(-a\right)a^{1-1}$$

2 ni 9 marotabaga ko'paytirish.

$$18a^{2-1}+\left(-a\right)a^{1-1}$$

2 dan 1 ni ayirish.

$$18a^{1}+\left(-a\right)a^{1-1}$$

1 dan 1 ni ayirish.

$$18a^{1}+\left(-a\right)a^{0}$$

Har qanday t sharti uchun t^{1}=t.

$$18a+\left(-a\right)a^{0}$$

Har qanday t sharti uchun (0 bundan mustasno) t^{0}=1.

$$18a+\left(-a\right)\times 1$$

Har qanday t sharti uchun t\times 1=t va 1t=t.

$$18a-a$$
