Céimeanna Réitigh

Measc an tsuim téarma fá téarma.

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

Fág an leanúnach sna téarmaí as an áireamh.

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

Athscríobh \sqrt{x} mar x^{\frac{1}{2}}. Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{\frac{1}{2}}\mathrm{d}x le \frac{x^{\frac{3}{2}}}{\frac{3}{2}}. Simpligh.

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

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{\frac{4}{3}}\mathrm{d}x le \frac{3x^{\frac{7}{3}}}{7}.

$$\frac{2x^{\frac{3}{2}}}{3}+\frac{3x^{\frac{7}{3}}}{7}+3\int x^{\frac{3}{2}}\mathrm{d}x$$

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{\frac{3}{2}}\mathrm{d}x le \frac{2x^{\frac{5}{2}}}{5}. Méadaigh 3 faoi \frac{2x^{\frac{5}{2}}}{5}.

$$\frac{2x^{\frac{3}{2}}}{3}+\frac{3x^{\frac{7}{3}}}{7}+\frac{6x^{\frac{5}{2}}}{5}$$

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.
