(1/z)^2 eching

$$( \frac { 1 } { z } ) ^ { 2 }$$

Baholash

$$\frac{1}{z^{2}}$$

Oshib boruvchi tartibdan boshqa tartib uchun qadamlar

Ifodani qisqartirish uchun eksponent qoidalaridan foydalanish.

$$\left(\frac{1}{z}\right)^{2}$$

Daraja ko‘rsatkichini boshqa ko‘rsatkichga oshirish uchun, darajalarini ko‘paytiring.

$$z^{-2}$$

-1 ni 2 marotabaga ko'paytirish.

$$\frac{1}{z^{2}}$$

Oshib boruvchi koeffitsientdan tartib uchun qadamlar

Ifodani qisqartirish uchun eksponent qoidalaridan foydalanish.

$$\left(\frac{1}{z^{1}}\right)^{2}$$

Ikki aqam koeffitsientini daraja ko'rsatkichiga oshirish uchun har bir raqamni daraja ko'rsatkichiga oshiring, so'ngra bo'ling.

$$\frac{1^{2}}{\left(z^{1}\right)^{2}}$$

Daraja ko‘rsatkichini boshqa ko‘rsatkichga oshirish uchun, darajalarini ko‘paytiring.

$$\frac{1}{z^{2}}$$

z ga nisbatan hosilani topish

$$-\frac{2}{z^{3}}$$

Zanjirli qoidadan foydalanish qadamalari

Agar F ikki differensial funksiya f\left(u\right) va u=g\left(x\right)'ning yig'indisi bo'lsa, ya'ni agar F\left(x\right)=f\left(g\left(x\right)\right) bo'lsa, F hosilasi f'ning u martalik hosilasi, g'ning x martalik hosilasi ya'ni \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right) bo'ladi.

$$2\times \left(\frac{1}{z}\right)^{2-1}\frac{\mathrm{d}}{\mathrm{d}z}(\frac{1}{z})$$

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

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

Qisqartirish.

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

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

$$-2z^{-2}\times \frac{1}{z}$$
