$$\int x+\sqrt[3]{x}+\frac{1}{x^{2}}\mathrm{d}x$$

Kōmitimititia te kīanga tapeke mā te kīanga.

$$\int x\mathrm{d}x+\int \sqrt[3]{x}\mathrm{d}x+\int \frac{1}{x^{2}}\mathrm{d}x$$

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}.

$$\frac{x^{2}}{2}+\int \sqrt[3]{x}\mathrm{d}x+\int \frac{1}{x^{2}}\mathrm{d}x$$

Tuhia anō te \sqrt[3]{x} hei x^{\frac{1}{3}}. Nā te mea \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} mō te k\neq -1, me whakakapi \int x^{\frac{1}{3}}\mathrm{d}x ki te \frac{x^{\frac{4}{3}}}{\frac{4}{3}}. Whakarūnātia.

$$\frac{x^{2}}{2}+\frac{3x^{\frac{4}{3}}}{4}+\int \frac{1}{x^{2}}\mathrm{d}x$$

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