Vedclass · Answer

(D) $I = \int \frac{d x}{\sqrt{\sin ^3 x \cos (x-\alpha)}}$$\cos(x-\alpha) = \cos x \cos \alpha + \sin x \sin \alpha$ નિત્યસમનો ઉપયોગ કરતા:$I = \int \frac{d x}{\sqrt{\sin ^3 x (\cos x \cos \alpha + \sin x \sin \alpha)}}$કૌંસમાંથી $\sin x$ સામાન્ય લેતા:$I = \int \frac{d x}{\sqrt{\sin ^4 x (\cot x \cos \alpha + \sin \alpha)}} = \int \frac{\csc^2 x}{\sqrt{\cot x \cos \alpha + \sin \alpha}} d x$ધારો કે $t = \cot x \cos \alpha + \sin \alpha$.તેથી $dt = -\csc^2 x \cos \alpha \, dx$,જેનો અર્થ છે કે $\csc^2 x \, dx = -\frac{dt}{\cos \alpha}$.આ કિંમતો સંકલનમાં મૂકતા:$I = \int \frac{-dt}{\cos \alpha \sqrt{t}} = -\frac{1}{\cos \alpha} \int t^{-1/2} dt$$I = -\frac{1}{\cos \alpha} (2 \sqrt{t}) + C = -\frac{2}{\cos \alpha} \sqrt{\cot x \cos \alpha + \sin \alpha} + C$વર્ગમૂળમાંથી $\cos \alpha$ સામાન્ય લેતા:$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$
