Koʻpaytma uchun derivativ qoidasidan foydalanish qadamlari

Har qanday ikki differensial funksiya uchun, ikki funksiya koʻpaytmasining hosilasi birinchi funksiya marotabasi, ikkinchi plyus hosilasi ikkinchi funksiya marotabasi birinchining hosilasidir.

$$\left(3x^{-6}+12\right)\frac{\mathrm{d}}{\mathrm{d}x}(-5x^{-10}-8)+\left(-5x^{-10}-8\right)\frac{\mathrm{d}}{\mathrm{d}x}(3x^{-6}+12)$$

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

$$\left(3x^{-6}+12\right)\left(-10\right)\left(-5\right)x^{-10-1}+\left(-5x^{-10}-8\right)\left(-6\right)\times 3x^{-6-1}$$

Qisqartirish.

$$\left(3x^{-6}+12\right)\times 50x^{-11}+\left(-5x^{-10}-8\right)\left(-18\right)x^{-7}$$

3x^{-6}+12 ni 50x^{-11} marotabaga ko'paytirish.

$$3x^{-6}\times 50x^{-11}+12\times 50x^{-11}+\left(-5x^{-10}-8\right)\left(-18\right)x^{-7}$$

-5x^{-10}-8 ni -18x^{-7} marotabaga ko'paytirish.

$$3x^{-6}\times 50x^{-11}+12\times 50x^{-11}-5x^{-10}\left(-18\right)x^{-7}-8\left(-18\right)x^{-7}$$

Ayni daraja ko'rsatkichlarini ko'paytirish uchun ularning darajalarini qo'shing.

$$50\times 3x^{-6-11}+50\times 12x^{-11}-5\left(-18\right)x^{-10-7}-8\left(-18\right)x^{-7}$$

Qisqartirish.

$$150x^{-17}+600x^{-11}+90x^{-17}+144x^{-7}$$
