You can solve it like this using rational or floats: In [9]: solve(Eq((1-(x**2))**(S(1)/2), S(1)/2), x) Out[9]: ⎡-√3 √3⎤ ⎢────, ──⎥ ⎣ 2 2 ⎦ In [10]: solve(Eq((1.0-(x**2))**0.5, 0.5), x) Out[10]: [-0.866025403784439, 0.866025403784439] -- You received this message because you are subscribed to the Google Groups "sympy" group.
