3(1)^3+k(1)+2 eching

$$3 ( 1 ) ^ { 3 } + k ( 1 ) + 2$$

k ga nisbatan hosilani topish

$$1$$

Yig'indi uchun derivativ qoidasidan foydalanish qadamlari

3 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.

$$\frac{\mathrm{d}}{\mathrm{d}k}(3\times 1+k\times 1+2)$$

3 hosil qilish uchun 3 va 1 ni ko'paytirish.

$$\frac{\mathrm{d}}{\mathrm{d}k}(3+k\times 1+2)$$

5 olish uchun 3 va 2'ni qo'shing.

$$\frac{\mathrm{d}}{\mathrm{d}k}(5+k\times 1)$$

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

$$k^{1-1}$$

1 dan 1 ni ayirish.

$$k^{0}$$

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

$$1$$
