Measc an tsuim téarma fá téarma.

$$\int 2x^{5}\mathrm{d}x+\int \frac{3}{x}\mathrm{d}x+\int \frac{1}{x^{9}}\mathrm{d}x$$

Fág an leanúnach sna téarmaí as an áireamh.

$$2\int x^{5}\mathrm{d}x+3\int \frac{1}{x}\mathrm{d}x+\int \frac{1}{x^{9}}\mathrm{d}x$$

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 2 faoi \frac{x^{6}}{6}.

$$\frac{x^{6}}{3}+3\int \frac{1}{x}\mathrm{d}x+\int \frac{1}{x^{9}}\mathrm{d}x$$

Bain úsáid as \int \frac{1}{x}\mathrm{d}x=\ln(|x|) ón tábla do suimeálaithe coitianta chun an toradh a fháil.

$$\frac{x^{6}}{3}+3\ln(|x|)+\int \frac{1}{x^{9}}\mathrm{d}x$$

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int \frac{1}{x^{9}}\mathrm{d}x le -\frac{1}{8x^{8}}.

$$\frac{x^{6}}{3}+3\ln(|x|)-\frac{1}{8x^{8}}$$

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.

$$\frac{x^{6}}{3}+3\ln(|x|)-\frac{1}{8x^{8}}+С$$
