Comment #4 on issue 1868 by [email protected]: solve(floating point,
x) stopped working
http://code.google.com/p/sympy/issues/detail?id=1868
Ok, fixed the problem in Issue 1897, but don't that one (Issue 1880, but
with evalf):
from sympy import *
E = Symbol('E')
J = Symbol('J')
F = Symbol('F')
lmbda = Symbol('lambda')
L = Symbol('L')
f = -21601054687500000000*E**8*J**8/L**16 +
508232812500000000*F*lmbda*E**7*J**7/
L**14 - 4269543750000000*E**6*F**2*J**6*lmbda**2/L**12 +
16194716250000*E**5*F**3*J**5*lmbda**3/L**10 -
27633173750*E**4*F**4*J**4*lmbda**4/
L**8 + 14840215*E**3*F**5*J**3*lmbda**5/L**6 +
54794*E**2*F**6*J**2*lmbda**6/
(5*L**4) - 1153*E*J*F**7*lmbda**7/(80*L**2)+ 633*F**8*lmbda**8/160000
print solve(f.evalf(), lmbda)
