Passi tas-Soluzzjonijiet

L-ewwel evalwa l-integru indefinit.

$$\int x^{2}+2+3x^{4}+2e^{9}\mathrm{d}x$$

Tintegra s-somma terminu b'terminu.

$$\int x^{2}\mathrm{d}x+\int 2\mathrm{d}x+\int 3x^{4}\mathrm{d}x+\int 2e^{9}\mathrm{d}x$$

Iffattura ‘l barra l-kostanti f’kull wieħed minn dawn it-termini.

$$\int x^{2}\mathrm{d}x+\int 2\mathrm{d}x+3\int x^{4}\mathrm{d}x+2\int e^{9}\mathrm{d}x$$

Minn \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} għal k\neq -1, issostitwixxi \int x^{2}\mathrm{d}x ma' \frac{x^{3}}{3}.

$$\frac{x^{3}}{3}+\int 2\mathrm{d}x+3\int x^{4}\mathrm{d}x+2\int e^{9}\mathrm{d}x$$

Sib l-integru ta' 2 billi tuża t-tabella tar-regola tal-integrali komuni \int a\mathrm{d}x=ax.

$$\frac{x^{3}}{3}+2x+3\int x^{4}\mathrm{d}x+2\int e^{9}\mathrm{d}x$$

Minn \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} għal k\neq -1, issostitwixxi \int x^{4}\mathrm{d}x ma' \frac{x^{5}}{5}. Immultiplika 3 b'\frac{x^{5}}{5}.

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

Sib l-integru ta' e^{9} billi tuża t-tabella tar-regola tal-integrali komuni \int a\mathrm{d}x=ax.

$$\frac{x^{3}}{3}+2x+\frac{3x^{5}}{5}+2e^{9}x$$

L-integru definit huwa l-antiderivattiv tal-espressjoni evalwata fil-limitu superjuri tal-integrazzjoni minus l-antiderivattiv evalwat fil-limitu inferjuri tal-integrazzjoni.

$$\frac{100^{3}}{3}+2\times 100+\frac{3}{5}\times 100^{5}+2e^{9}\times 100-\left(\frac{0^{3}}{3}+2\times 0+\frac{3}{5}\times 0^{5}+2e^{9}\times 0\right)$$

Issimplifika.

$$\frac{18001000600}{3}+200e^{9}$$
