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}.

$$2\times 25x^{2-1}-9x^{1-1}$$

2 ni 25 marotabaga ko'paytirish.

$$50x^{2-1}-9x^{1-1}$$

2 dan 1 ni ayirish.

$$50x^{1}-9x^{1-1}$$

1 dan 1 ni ayirish.
