Indeed, thanks for reporting it!
While Ondrej is on mountains, I've created a mirror so that you can

It doesn't do that anymore,
Hello!
Is there any way to instruct sympy to use real numbers only?
In [1]: from sympy import *
In [2]: x = Symbol('x', real=True)
In [3]: sqrt(x**2-3)
Out[3]: I*(3 - x**2)**(1/2)
Why is sqrt(x**2-3) transformed in that way that it uses the imaginary
unit? This makes it hard for me to turn t
Hello!

I just noticed that as_expr_orders() is failing at the moment.
The following small patch made it work again:

On adding to asin and acos, we should at least check whether the value
passed lies between -1 and

This is what I am doing:
>>> from sympy import *
>>> x = Symbol("x",ispositive=True)
>>> y = Symbol("y",isnegative=True)
>>> min(x,y)
x
>>> max(x,y)
y
>>> min(y,0)
0
>>> max(y,0)
y
I'm guessing that SymPy views the symbols x and y as formal variables,
e.g., formal variables for creating a ring
