Hi all,
Just ran into this:
>>> from sympy import solve
>>> solve(2*x*cos(2*x) + sin(2*x))
Traceback (most recent call last):
File "<pyshell#65>", line 1, in <module>
solve(2*x*cos(2*x) + sin(2*x))
File
"/usr/lib/python3.3/site-packages/sympy-0.7.6_git-py3.3.egg/sympy/solvers/solvers.py",
line 912, in solve
solution = _solve(f[0], *symbols, **flags)
File
"/usr/lib/python3.3/site-packages/sympy-0.7.6_git-py3.3.egg/sympy/solvers/solvers.py",
line 1307, in _solve
return _solve(newf, symbol, **flags)
File
"/usr/lib/python3.3/site-packages/sympy-0.7.6_git-py3.3.egg/sympy/solvers/solvers.py",
line 1423, in _solve
"\nNo algorithms are implemented to solve equation %s" % f)
NotImplementedError: multiple generators [x, tan(x)]
No algorithms are implemented to solve equation 2*x*(-tan(x)**2 +
1)/(tan(x)**2 + 1) + 2*tan(x)/(tan(x)**2 + 1)
Thanks for any insights into this and whether there is a workaround.
Best,
Amit.
