Measc an tsuim téarma fá téarma.

$$\int 7x^{2}\mathrm{d}x+\int -3x^{3}\mathrm{d}x+\int 4x^{5}\mathrm{d}x$$

Fág an leanúnach sna téarmaí as an áireamh.

$$7\int x^{2}\mathrm{d}x-3\int x^{3}\mathrm{d}x+4\int x^{5}\mathrm{d}x$$

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{2}\mathrm{d}x le \frac{x^{3}}{3}. Méadaigh 7 faoi \frac{x^{3}}{3}.

$$\frac{7x^{3}}{3}-3\int x^{3}\mathrm{d}x+4\int x^{5}\mathrm{d}x$$

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{3}\mathrm{d}x le \frac{x^{4}}{4}. Méadaigh -3 faoi \frac{x^{4}}{4}.

$$\frac{7x^{3}}{3}-\frac{3x^{4}}{4}+4\int x^{5}\mathrm{d}x$$

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{5}\mathrm{d}x le \frac{x^{6}}{6}. Méadaigh 4 faoi \frac{x^{6}}{6}.

$$\frac{7x^{3}}{3}-\frac{3x^{4}}{4}+\frac{2x^{6}}{3}$$

Má tá F\left(x\right) mar frithdhíorthach do f\left(x\right), beidh tacar do frithdhíorthach uile do f\left(x\right) a thabhairt ag F\left(x\right)+C. Mar sin de, cur an comhtháthú leanúnach C\in \mathrm{R} don toradh.
