$$\int 1.2x^{2}+32x+186\mathrm{d}x$$

Kōmitimititia te kīanga tapeke mā te kīanga.

$$\int \frac{6x^{2}}{5}\mathrm{d}x+\int 32x\mathrm{d}x+\int 186\mathrm{d}x$$

Whakatauwehea te pūmau i ēnei kīanga katoa.

$$\frac{6\int x^{2}\mathrm{d}x}{5}+32\int x\mathrm{d}x+\int 186\mathrm{d}x$$

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

$$\frac{2x^{3}}{5}+32\int x\mathrm{d}x+\int 186\mathrm{d}x$$

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

$$\frac{2x^{3}}{5}+16x^{2}+\int 186\mathrm{d}x$$

Kimihia te tau tōpū o 186 mā te whakamahi i te ture mō te ripanga o ngā tau tōpū pātahi \int a\mathrm{d}x=ax.

$$\frac{2x^{3}}{5}+16x^{2}+186x$$

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.

$$\frac{2x^{3}}{5}+16x^{2}+186x+С$$

Kimi Pārōnaki e ai ki x
