# simplify sinh expression

I guess I just ran up against one of those maxima things again, but I thought I would signal the problem anyway.

I would have expected Sage to simplify

```
sinh(log(1+sqrt(2)))
```

(it is 1), but Sage doesn't. It doesn't return True to the following either

```
arcsinh(1)==1+sqrt(2)
```

or am I missing something?

sinh(log(1+sqrt(2))).n() 1.00000000000000
