y^2+3y+21 eching

$$y ^ { 2 } + 3 y + 21$$

y ga nisbatan hosilani topish

$$2y+3$$

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}.

$$2y^{2-1}+3y^{1-1}$$

2 dan 1 ni ayirish.

$$2y^{1}+3y^{1-1}$$

1 dan 1 ni ayirish.

$$2y^{1}+3y^{0}$$

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

$$2y+3y^{0}$$

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

$$2y+3\times 1$$

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

$$2y+3$$
