Let me add two remarks 1) the exact value of the jump position seems to be xj = 2^(2/3) - 1 N[2^(2/3) - 1, 20] (* 0.58740105196819947475 *) 2) an antiderivative without a jump can be calculated as follows ad2F1[x_] =...
Thanks, Daniel, for pointing out this site to me. It seems, however, that in contrast to StackExchangeMMA Latex is not supported here. Example: $\sqrt{1+x^2}$ Or am I doing something wrong? I have gradually become acustomed to using it...
Craig, you are right, it should. But many years of (good!) experience showed me that a prudent cooperation between Mathematica and the user is the best way to reach the goal. Sorry for "teaching" philosophy ;-) Regards, Wolfgang
