Whakaoti i te x^-2/x^-2+y^-2

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

Aromātai

$$\frac{y^{2}}{x^{2}+y^{2}}$$

Ngā Hipanga Rongoā Poto

Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.

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

Me whakakore tahi te x^{-2} i te taurunga me te tauraro.

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

Me whakaroha te kīanga.

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

Tuhia te \frac{1}{y}x hei hautanga kotahi.

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

Kia whakarewa i te \frac{x}{y} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.

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

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 1 ki te \frac{y^{2}}{y^{2}}.

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

Tā te mea he rite te tauraro o \frac{y^{2}}{y^{2}} me \frac{x^{2}}{y^{2}}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Whakawehe 1 ki te \frac{y^{2}+x^{2}}{y^{2}} mā te whakarea 1 ki te tau huripoki o \frac{y^{2}+x^{2}}{y^{2}}.

$$\frac{y^{2}}{y^{2}+x^{2}}$$

Kimi Pārōnaki e ai ki x

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