MyFunc(x).subs(x,zero). How to evaluate (not evalf but symbolically eg simplify)?
sec()function. Is there any reference I can look up to to get better understanding of the current algorithm implemented?
functions.cpp. See how the code progresses (manually) when the arguement 0 is passed. You can use
gdbif you like. Follow it properly, and you'll be able to figure out what's wrong. I think you'll have to take a look at the
evalfunction here, and see what it is returning, and what it should be returning.
