I have attempted to use this site to check (amongst other methods), but for the functions listed above (I have already verified arithmetic and the simpler functions myself) it cannot cope! Here are my results:

Code:

```
sinh: 1.249367 1.600287 1.249367 1.600287 1.249367 1.600287 1.249367
cosh: 1.600287 1.249367 1.600287 1.249367 1.600287 1.249367 1.600287
tanh: 0.655794 0.569934 -0.747519 0.330788 2.122361 -7.644586 2.875892
sech^2: 0.569934 -0.747519 0.330788 2.122361 -7.644586 2.875892 93.917658
