However, every now and again, there are moments such as the Friday Night Live! card at Southwell last week which lift the mood completely, and offer hope that a 250-year-old sport has plenty of running left to give.
To rigorously define inverse hyperbolic cosine, we need to make a branch cut. We cannot define arccosh as an analytic function over the entire complex plane. But if we remove (−∞, 1], we can. We define arccosh(x) for real x 1 to be the positive real number y such that cosh(y) = x, and define it for the rest of the complex plane (with our branch cut (−∞, 1] removed) by analytic continuation.。line 下載对此有专业解读
