# [with patch] integrate(1/sqrt(9+x^2)) fails

Reported by: Owned by: mhansen mhansen blocker sage-2.8.9 calculus

### Description

integrate(1/sqrt(9+x2)) x/3

I tried this at home and numerous times on sagenb.org. Every other plausible syntax of this integral I tried (-1 power, more parentheses, switch the summands, etc.) yields the same result

Here's the reason

```(%i1) integrate(1/sqrt(9+x^2),x)
;
x
(%o1)                              asinh(-)
3

```
