I'm trying to find this indefinite integral
$$\int\frac{\cos^{3/2} x}{\sin x\sqrt{(\lambda-2\cos x-2\ln(1-\cos x)+2\ln(\sin x))}} \,\mathrm dx$$
Or $$\int_0^{\pi/2}\frac{\cos^{3/2}x}{\sin x\sqrt{\lambda-2\cos x-2\ln(1-\cos x)+2\ln(\sin x)}}\,\mathrm dx$$
Where $\lambda>2$
Which sub I take !?
I don't have any ideas for this type integration
Please give me ideas
