u^2+3u+4 eching

$$u ^ { 2 } + 3 u + 4$$

u ga nisbatan hosilani topish

$$2u+3$$

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}.

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

2 dan 1 ni ayirish.

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

1 dan 1 ni ayirish.

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

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

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

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

$$2u+3\times 1$$

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

$$2u+3$$

Baholash

$$u^{2}+3u+4$$
