\int 3\mathrm{d}x+\int \frac{x}{2}\mathrm{d}x
Kōmitimititia te kīanga tapeke mā te kīanga.
\int 3\mathrm{d}x+\frac{\int x\mathrm{d}x}{2}
Whakatauwehea te pūmau i ēnei kīanga katoa.
3x+\frac{\int x\mathrm{d}x}{2}
Kimihia te tau tōpū o 3 mā te whakamahi i te ture mō te ripanga o ngā tau tōpū pātahi \int a\mathrm{d}x=ax.
3x+\frac{x^{2}}{4}
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 \frac{1}{2} ki te \frac{x^{2}}{2}.
3x+\frac{x^{2}}{4}+С
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.
