Ngā Upane Otinga

Whakamahia te ture huarua \left(a+b\right)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3} hei whakaroha \left(2x^{3}+5\right)^{3}.

$$\int 8\left(x^{3}\right)^{3}+60\left(x^{3}\right)^{2}+150x^{3}+125\mathrm{d}x$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 3 me te 3 kia riro ai te 9.

$$\int 8x^{9}+60\left(x^{3}\right)^{2}+150x^{3}+125\mathrm{d}x$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 3 me te 2 kia riro ai te 6.

$$\int 8x^{9}+60x^{6}+150x^{3}+125\mathrm{d}x$$

Kōmitimititia te kīanga tapeke mā te kīanga.

$$\int 8x^{9}\mathrm{d}x+\int 60x^{6}\mathrm{d}x+\int 150x^{3}\mathrm{d}x+\int 125\mathrm{d}x$$

Whakatauwehea te pūmau i ēnei kīanga katoa.

$$8\int x^{9}\mathrm{d}x+60\int x^{6}\mathrm{d}x+150\int x^{3}\mathrm{d}x+\int 125\mathrm{d}x$$

Nā te mea \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} mō te k\neq -1, me whakakapi \int x^{9}\mathrm{d}x ki te \frac{x^{10}}{10}. Whakareatia 8 ki te \frac{x^{10}}{10}.

$$\frac{4x^{10}}{5}+60\int x^{6}\mathrm{d}x+150\int x^{3}\mathrm{d}x+\int 125\mathrm{d}x$$

Nā te mea \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} mō te k\neq -1, me whakakapi \int x^{6}\mathrm{d}x ki te \frac{x^{7}}{7}. Whakareatia 60 ki te \frac{x^{7}}{7}.

$$\frac{4x^{10}}{5}+\frac{60x^{7}}{7}+150\int x^{3}\mathrm{d}x+\int 125\mathrm{d}x$$

Nā te mea \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} mō te k\neq -1, me whakakapi \int x^{3}\mathrm{d}x ki te \frac{x^{4}}{4}. Whakareatia 150 ki te \frac{x^{4}}{4}.

$$\frac{4x^{10}}{5}+\frac{60x^{7}}{7}+\frac{75x^{4}}{2}+\int 125\mathrm{d}x$$

Kimihia te tau tōpū o 125 mā te whakamahi i te ture mō te ripanga o ngā tau tōpū pātahi \int a\mathrm{d}x=ax.

$$\frac{4x^{10}}{5}+\frac{60x^{7}}{7}+\frac{75x^{4}}{2}+125x$$

Whakarūnātia.

$$125x+\frac{75x^{4}}{2}+\frac{60x^{7}}{7}+\frac{4x^{10}}{5}$$

Mēnā ko F\left(x\right) he pārōnaki kōaro o f\left(x\right), kāti ko te huinga o ngā pārōnaki kōaro katoa o f\left(x\right) ka whakaaturia e F\left(x\right)+C. Nō reira, me tāpiri te pūmau o te whakatōpūtanga C\in \mathrm{R} ki te otinga.

$$125x+\frac{75x^{4}}{2}+\frac{60x^{7}}{7}+\frac{4x^{10}}{5}+С$$
