Vedclass · Answer

(D) $I = \int \frac{d x}{\sqrt{\sin ^3 x \cos (x-\alpha)}}$$\cos(x-\alpha) = \cos x \cos \alpha + \sin x \sin \alpha$ सर्वसमिका का उपयोग करने पर:$I = \int \frac{d x}{\sqrt{\sin ^3 x (\cos x \cos \alpha + \sin x \sin \alpha)}}$कोष्ठक से $\sin x$ कॉमन लेने पर:$I = \int \frac{d x}{\sqrt{\sin ^4 x (\cot x \cos \alpha + \sin \alpha)}} = \int \frac{\csc^2 x}{\sqrt{\cot x \cos \alpha + \sin \alpha}} d x$माना $t = \cot x \cos \alpha + \sin \alpha$.तब $dt = -\csc^2 x \cos \alpha \, dx$,जिसका अर्थ है $\csc^2 x \, dx = -\frac{dt}{\cos \alpha}$.इन मानों को समाकलन में रखने पर:$I = \int \frac{-dt}{\cos \alpha \sqrt{t}} = -\frac{1}{\cos \alpha} \int t^{-1/2} dt$$I = -\frac{1}{\cos \alpha} (2 \sqrt{t}) + C = -\frac{2}{\cos \alpha} \sqrt{\cot x \cos \alpha + \sin \alpha} + C$वर्गमूल से $\cos \alpha$ कॉमन लेने पर:$I = -\frac{2}{\cos \alpha} \sqrt{\cos \alpha (\cot x + \frac{\sin \alpha}{\cos \alpha})} + C$$I = -\frac{2}{\sqrt{\cos \alpha}} \sqrt{\cot x + 	an \alpha} + C$

$\int \frac{d x}{\sqrt{\sin ^3 x \cos (x-\alpha)}}=$
