Réitigh ∫ (from 0 to 100) of (x^2+2+3x^4+2e^9) wrt x

$$\int _ { 0 } ^ { 100 } ( x ^ { 2 } + 2 + 3 x ^ { 4 } + 2 e ^ { 9 } ) d x$$

Luacháil

$$200e^{9}+\frac{18001000600}{3}\approx 6001954150.118847847$$

Céimeanna Réitigh

Déan luacháil ar an suimeálaí éiginnte ar dtús.

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

Measc an tsuim téarma fá téarma.

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

Fág an leanúnach sna téarmaí as an áireamh.

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

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}.

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

Aimsigh suimeálaithe do 2 ag baint úsáid as an tábla do suimeálaithe coitianta riail\int a\mathrm{d}x=ax.

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

Ó \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} fá choinne k\neq -1, athchuir \int x^{4}\mathrm{d}x le \frac{x^{5}}{5}. Méadaigh 3 faoi \frac{x^{5}}{5}.

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

Aimsigh suimeálaithe do e^{9} ag baint úsáid as an tábla do suimeálaithe coitianta riail\int a\mathrm{d}x=ax.

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

Is ionann suimeálaí cinnte agus frithdhíorthach an nath luacháilte ag teorainn uachtair na suimeála lúide an frithdhíorthach luacháilte ag teorainn íochtair na suimeála.

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

Simpligh.

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