Coxeter's integral

WebCoxeter's integral的形式为： I=\int_{0}^{\frac{\pi}{2}}\cos^{-1}({\frac{\cos{}x}{1+2\cos{x}})}dx 如果我们要去解这个积分，首先第一步这个积分是不可能直接被解出来的，arccos的形 … Web3 Answers. Sorted by: 4. Your first example (Archimedes) makes use of cos x / cos x. There are many further possible functions like f ( x) / f ( x) or f ( x) + C − f ( x) leading to trivial integrals. Cavalieri’s principle comes to mind: The slices of sphere and conus inscribed into a cylinder being equal to the slice of the cylinder.
