```
a,x=Symbol('a x')
integrate(sqrt(x/(a-x)),x)
```
Result:
```
Integral(sqrt(x/(a-x))
```
Wolfram alpha is able to do this (GIF of result attached).
BTW, this integral appears when calcul…

A couple of leftovers from #337.
gcd(a^a,a^(a-1)) => a should=> a^(a-1)
My implementation for gcd of EX is mainly targetted for gcd(2^a,6^a) => 2^a
And Wolfram Alpha gives gcd(2^a,6^(a-2)) => 2…

Hello, my example cases for exponential regression are giving incorrect results. Would it be possible for someone to check the algorithm on this? (Wolfram alpha gives correct results on this data, so …

It appears that currently sympy can't solve equations of the form 4^x + 6^x == 9^x. However they are solved by

Instead, it is interpreted as a function x evaluated at point x, which breaks the rule of least surprise _(edit: at least for mathematicians, which are certainly one target group)_.

Hello,
I've been looking at frameworks for natural language date parsing, and natty seems to be the most promising one I've found. I've also looked closely at DateJS, Chronic, and Wolfram|Alpha.
