Whakaoti i te f(x)=2x/1-x^2

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

Kimi Pārōnaki e ai ki x

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

Ngā Upane e Whakamahi ana i te Ture Pārōnaki mō te Otinga

Mō ngā pānga e rua e taea ana te pārōnaki, ko te pārōnaki o te otinga o ngā pānga e rua ko te tauraro whakareatia ki te pārōnaki o te taurunga tango i te taurunga whakareatia ki te pārōnaki o te tauraro, ā, ka whakawehea te katoa ki te tauraro kua pūruatia.

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

Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.

Whakarohaina mā te āhuatanga tohatoha.

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

Hei whakarea pū o te pūtake ōrite, tāpiri ana taupū.

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

Mahia ngā tātaitanga.

$$\frac{-2x^{2}+2x^{0}-\left(-4x^{2}\right)}{\left(-x^{2}+1\right)^{2}}$$

Pahekotia ngā kīanga tau ōrite.

$$\frac{\left(-2-\left(-4\right)\right)x^{2}+2x^{0}}{\left(-x^{2}+1\right)^{2}}$$

Tango -4 mai i -2.

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

Tauwehea te 2.

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

Mō tētahi kupu t mahue te 0, t^{0}=1.
