Vedclass · Answer

(C) ધારો કે $I = \int \frac{dx}{(1+\sqrt{x}) \sqrt{x(1-x)}} = \int \frac{dx}{(1+\sqrt{x}) \sqrt{x} \sqrt{1-x}}$.$\sqrt{x} = t$ આદેશ લેતા,$\frac{1}{2\sqrt{x}} dx = dt$,તેથી $\frac{dx}{\sqrt{x}} = 2dt$.સંકલન $I = \int \frac{2dt}{(1+t) \sqrt{1-t^2}}$ બને છે.વધુમાં,$t = \sin 	heta$ આદેશ લેતા,$dt = \cos 	heta d	heta$.$I = \int \frac{2 \cos 	heta d	heta}{(1+\sin 	heta) \sqrt{1-\sin^2 	heta}} = \int \frac{2 \cos 	heta d	heta}{(1+\sin 	heta) \cos 	heta} = 2 \int \frac{d	heta}{1+\sin 	heta}$.$1+\sin 	heta = 1+\cos(\frac{\pi}{2}-	heta) = 2 \cos^2(\frac{\pi}{4}-\frac{	heta}{2})$ નો ઉપયોગ કરતા,$I = \int \sec^2(\frac{\pi}{4}-\frac{	heta}{2}) d	heta$.સંકલન કરતા,$I = -2 	an(\frac{\pi}{4}-\frac{	heta}{2}) + c = -2 \sqrt{\frac{1-\sqrt{x}}{1+\sqrt{x}}} + c$.
