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}.

$$2\times 13x^{2-1}+4x^{1-1}$$

2 ni 13 marotabaga ko'paytirish.

$$26x^{2-1}+4x^{1-1}$$

2 dan 1 ni ayirish.

$$26x^{1}+4x^{1-1}$$

1 dan 1 ni ayirish.

$$26x^{1}+4x^{0}$$

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

$$26x+4x^{0}$$

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

$$26x+4\times 1$$

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

$$26x+4$$
