New issue 3265 by [email protected]: Limit computation fails http://code.google.com/p/sympy/issues/detail?id=3265 The limit in Gruntz 7.6 fails: In [11]: L = z / (sqrt(1+z)*sin(a)**2+sqrt(1 z)*cos(a)**2-1) In [14]: gruntz(L, z, 0) Out[14]: 0 Instead of the correct result 2 / (1-2*cos(a)**2) = -2*sec(2*a). Recognising the zero works: In [15]: sin(z)**2 + cos(z)**2 -1 Out[15]: sin(z)**2 + cos(z)**2 - 1 In [16]: simplify(_) Out[16]: 0 -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
