Céimeanna Réitigh

Fág an úsáid leanúnach do\int af\left(\theta \right)\mathrm{d}\theta =a\int f\left(\theta \right)\mathrm{d}\theta as an áireamh.

$$2\int \theta \mathrm{d}\theta$$

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

$$\theta ^{2}$$

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