Koeffitsient uchun derivativ qoidasidan foydalanish qadamlari

Har qanday ikki differensial funksiya uchun ikki funksiyaning koeffitsient hosilasi raqamlagichning hosila marotabasi maxraj minusi va barchasi kvadrat maxrajiga bo'lingan.

$$\frac{\left(x^{2}+8x^{1}\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{1})-x^{1}\frac{\mathrm{d}}{\mathrm{d}x}(x^{2}+8x^{1})}{\left(x^{2}+8x^{1}\right)^{2}}$$

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

$$\frac{\left(x^{2}+8x^{1}\right)x^{1-1}-x^{1}\left(2x^{2-1}+8x^{1-1}\right)}{\left(x^{2}+8x^{1}\right)^{2}}$$

Qisqartirish.

$$\frac{\left(x^{2}+8x^{1}\right)x^{0}-x^{1}\left(2x^{1}+8x^{0}\right)}{\left(x^{2}+8x^{1}\right)^{2}}$$

x^{2}+8x^{1} ni x^{0} marotabaga ko'paytirish.

$$\frac{x^{2}x^{0}+8x^{1}x^{0}-x^{1}\left(2x^{1}+8x^{0}\right)}{\left(x^{2}+8x^{1}\right)^{2}}$$

x^{1} ni 2x^{1}+8x^{0} marotabaga ko'paytirish.

$$\frac{x^{2}x^{0}+8x^{1}x^{0}-\left(x^{1}\times 2x^{1}+x^{1}\times 8x^{0}\right)}{\left(x^{2}+8x^{1}\right)^{2}}$$

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

$$\frac{x^{2}+8x^{1}-\left(2x^{1+1}+8x^{1}\right)}{\left(x^{2}+8x^{1}\right)^{2}}$$

Qisqartirish.

$$\frac{x^{2}+8x^{1}-\left(2x^{2}+8x^{1}\right)}{\left(x^{2}+8x^{1}\right)^{2}}$$

O'xshash hadlarni birlashtirish.

$$\frac{-x^{2}}{\left(x^{2}+8x^{1}\right)^{2}}$$

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

$$\frac{-x^{2}}{\left(x^{2}+8x\right)^{2}}$$
