Ngā Upane Otinga

Aromātaitia te tau tōpū tautuhi-kore i te tuatahi.

$$\int 3x^{3}-x^{2}+2x-4\mathrm{d}x$$

Kōmitimititia te kīanga tapeke mā te kīanga.

$$\int 3x^{3}\mathrm{d}x+\int -x^{2}\mathrm{d}x+\int 2x\mathrm{d}x+\int -4\mathrm{d}x$$

Whakatauwehea te pūmau i ēnei kīanga katoa.

$$3\int x^{3}\mathrm{d}x-\int x^{2}\mathrm{d}x+2\int x\mathrm{d}x+\int -4\mathrm{d}x$$

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 3 ki te \frac{x^{4}}{4}.

$$\frac{3x^{4}}{4}-\int x^{2}\mathrm{d}x+2\int x\mathrm{d}x+\int -4\mathrm{d}x$$

Nā te mea \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} mō te k\neq -1, me whakakapi \int x^{2}\mathrm{d}x ki te \frac{x^{3}}{3}. Whakareatia -1 ki te \frac{x^{3}}{3}.

$$\frac{3x^{4}}{4}-\frac{x^{3}}{3}+2\int x\mathrm{d}x+\int -4\mathrm{d}x$$

Nā te mea \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} mō te k\neq -1, me whakakapi \int x\mathrm{d}x ki te \frac{x^{2}}{2}. Whakareatia 2 ki te \frac{x^{2}}{2}.

$$\frac{3x^{4}}{4}-\frac{x^{3}}{3}+x^{2}+\int -4\mathrm{d}x$$

Kimihia te tau tōpū o -4 mā te whakamahi i te ture mō te ripanga o ngā tau tōpū pātahi \int a\mathrm{d}x=ax.

$$\frac{3x^{4}}{4}-\frac{x^{3}}{3}+x^{2}-4x$$

Ko te tau tōpū tautuhi ko te pārōnaki kōaro o te kīanga i aromātaitia i te tepe tōrunga o te pāwhaitua, tangohia te pārōnaki kōaro i aromātaitia i te tepe tōraro o te pāwhaitua.

$$\frac{3}{4}\times 1^{4}-\frac{1^{3}}{3}+1^{2}-4-\left(\frac{3}{4}\times 0^{4}-\frac{0^{3}}{3}+0^{2}-4\times 0\right)$$

Whakarūnātia.
