f(x)=-x^2/2x^2+1= eching

$$f ( x ) = \frac { - x ^ { 2 } } { 2 x ^ { 2 } + 1 } =$$

x ga nisbatan hosilani topish

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

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.

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

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

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

Arifmetik hisobni amalga oshirish.

$$\frac{\left(2x^{2}+1\right)\left(-2\right)x^{1}-\left(-x^{2}\times 4x^{1}\right)}{\left(2x^{2}+1\right)^{2}}$$

Distributiv xususiyatdan foydalanib kengaytirish.

$$\frac{2x^{2}\left(-2\right)x^{1}-2x^{1}-\left(-x^{2}\times 4x^{1}\right)}{\left(2x^{2}+1\right)^{2}}$$

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

$$\frac{2\left(-2\right)x^{2+1}-2x^{1}-\left(-4x^{2+1}\right)}{\left(2x^{2}+1\right)^{2}}$$

Arifmetik hisobni amalga oshirish.

$$\frac{-4x^{3}-2x^{1}-\left(-4x^{3}\right)}{\left(2x^{2}+1\right)^{2}}$$

O'xshash hadlarni birlashtirish.

$$\frac{\left(-4-\left(-4\right)\right)x^{3}-2x^{1}}{\left(2x^{2}+1\right)^{2}}$$

-4 dan -4 ni ayirish.

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

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

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

Baholash

$$-\frac{x^{2}}{2x^{2}+1}$$
