我正在尝试使用SymPy在python中解决方程式.我有一个生成的等式(function = y(8.0-(y**3.0))我和SymPy一起用来创建一个像这样的新等式:eq = sympy.Eq(function, 2)输出y(8.0-(y**3.0)) == 2.但sympy.solve(eq)似乎不起作用.
>>> from sympy import Eq, Symbol as sym, solve
>>> y = sym('y')
>>> eqa = Eq(y(8.0-(y**3.0)), 8)
>>> solve(eqa)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/pymodules/python2.6/sympy/solvers/solvers.py", line 332, in solve
result = tsolve(f, *symbols)
File "/usr/lib/pymodules/python2.6/sympy/solvers/solvers.py", line 716, in tsolve
raise NotImplementedError("Unable to solve the equation.")
NotImplementedError: Unable to solve the equation.
谢谢阅读.
