Dear Sympy community,
The following line of code gives:
>>> from sympy import *
>>> x,y=symbols('x y')
>>> f=lambdify(x,y*cos(x))
>>> f(1)
0.54030230586814*y
works fine, but interchanging x and y:
>>> f=lambdify(x,x*cos(y))
>>> f(1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1, in <lambda>
File
"/Users/krol/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/sympy/core/expr.py",
line 225, in __float__
raise TypeError("can't convert expression to float")
TypeError: can't convert expression to float
gives me a headache,
Does someone know a solution to this?
kind Regards,
Quirine
