Whakaoti i te ∫ (from - 1 to 073) of -1/2x^3+3x-2 wrt x

$$\int _ { - 1 } ^ { 073 } - \frac { 1 } { 2 } x ^ { 3 } + 3 x - 2 d x$$

Ngā Upane Otinga

Aromātaitia te tau tōpū tautuhi-kore i te tuatahi.

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

Kōmitimititia te kīanga tapeke mā te kīanga.

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

Whakatauwehea te pūmau i ēnei kīanga katoa.

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

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 -\frac{1}{2} ki te \frac{x^{4}}{4}.

$$-\frac{x^{4}}{8}+3\int x\mathrm{d}x+\int -2\mathrm{d}x$$

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 3 ki te \frac{x^{2}}{2}.

$$-\frac{x^{4}}{8}+\frac{3x^{2}}{2}+\int -2\mathrm{d}x$$

Kimihia te tau tōpū o -2 mā te whakamahi i te ture mō te ripanga o ngā tau tōpū pātahi \int a\mathrm{d}x=ax.

$$-\frac{x^{4}}{8}+\frac{3x^{2}}{2}-2x$$

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.

$$-\frac{1}{8}\times \left(0\times 73\right)^{4}+\frac{3}{2}\times \left(0\times 73\right)^{2}-2\times 0\times 73-\left(-\frac{\left(-1\right)^{4}}{8}+\frac{3}{2}\left(-1\right)^{2}-2\left(-1\right)\right)$$

Whakarūnātia.
