New issue 2809 by asmeu...@gmail.com: evalf() doesn't go all the way
http://code.google.com/p/sympy/issues/detail?id=2809
In [53]: 2*pi*I*(cos(k*abs(a)*I)/(2*abs(a)*I*(b**2 - a**2)) +
cos(k*abs(b)*I)/(2*abs(b)*I*(a**2 - b**2))).subs({a:1, b:2, k:3}).evalf()
Out[53]: -30.2633853551501⋅π
In [54]: 2*pi*I*(cos(k*abs(a)*I)/(2*abs(a)*I*(b**2 - a**2)) +
cos(k*abs(b)*I)/(2*abs(b)*I*(a**2 - b**2))).evalf(subs={a:1, b:2, k:3})
Out[54]: -30.2633853551501⋅π
In [55]: pi.evalf()
Out[55]: 3.14159265358979
In [56]: 2*pi*I*(cos(k*abs(a)*I)/(2*abs(a)*I*(b**2 - a**2)) +
cos(k*abs(b)*I)/(2*abs(b)*I*(a**2 - b**2))).evalf(subs={a:1, b:2,
k:3}).evalf()
Out[56]: -30.2633853551501⋅π
I can't get it to evaluate the pi.
