$\int_{\frac{π}{3}}^{\frac{π}{2}} \frac{\cot (x)}{\sqrt{1 + \sin^{2} (x)}} d x$

Etapa 1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ para reescrever $\sqrt{1 + \sin^{2} (x)}$ como ${(1 + \sin^{2} (x))}^{\frac{1}{2}}$ .

$\frac{d}{d x} [\int_{\frac{π}{3}}^{\frac{π}{2}} \frac{\cot (x)}{{(1 + \sin^{2} (x))}^{\frac{1}{2}}} d x]$

Etapa 2

Quando $\int_{\frac{π}{3}}^{\frac{π}{2}} \frac{\cot (x)}{{(1 + \sin^{2} (x))}^{\frac{1}{2}}} d x$ for avaliada, será constante com relação a $x$ . Portanto, a derivada de $\int_{\frac{π}{3}}^{\frac{π}{2}} \frac{\cot (x)}{{(1 + \sin^{2} (x))}^{\frac{1}{2}}} d x$ com relação a $x$ será $0$ .
