@José, as a tip for next time: usually people don't really need the message text; it suffices to just get the message name, which you can get in current versions by clicking the "..." icon to the left of an error message, and then clicking on "Copy Message Name" in the resulting popup menu. In older versions, it's the part with :: before the actual error message (e.g. Power::infy when you try evaluating 1/0).

| Nov 11, 2017 at 10:25 | comment | added | Henrik Schumacher | @JoséAntonioDíazNavas Ha, that's precisely what I thought. Well, it made us looking at it again and to correct another error, so it's okay. | |
| Nov 11, 2017 at 10:23 | comment | added | José Antonio Díaz Navas | @J.M. I apologize. My kernel was not clear :(( Anyway the error I obtain was too complex to be included in a comment | |
| Nov 11, 2017 at 10:23 | comment | added | Henrik Schumacher | @J.M. Oh my. Thank you for the constructive remark! I hope it's better now... | |

Ah, I see now. @Henrik, it should be F[t, a], not F[a, t] in your integral. In the meantime, let me also present this alternate formula: Integrate[(Function[{x, y, z}, x] @@ F[t, a]) Norm[Cross @@ Transpose[DF[t, a]]], {a, 1/2, 1}, {t, π/6, π/4}]

| Nov 11, 2017 at 10:04 | comment | added | José Antonio Díaz Navas | @Hedgehog I have checked this code and it does not work. | |

| Nov 10, 2017 at 16:53 | comment | added | Hedgehog | Thanks for the answer. It does not what I need, however you should add (3*t+1) factor to jacobidet | |
