New issue 3211 by 521...@gmail.com: when using integrate, 'tuple' object
has no attribute 'has'
http://code.google.com/p/sympy/issues/detail?id=3211
I have found the same issues but I still can't solve the problem, could
anyone help me?
B = integrate( integrate(1/2*y**2/(y**2+(L-r+x)**2)^(2/3),(x,-0.05,0.05)) ,
(y, 1,2))
the above expression result in the error:
AttributeError: 'tuple' object has no attribute 'has'
the code is in the file sympy/integrals/risch.py , line 35
I change the code "for f.has(x)" to "for x in f", the error remains, why?
Could someone give me an answer about it?
