Once in a while a face a problem with Mathematica in which I cannot
get a straightforward numerical output.
I have a function defined in mathematica, I try to evaluate the
function with numerical arguments and mathematica returns a replica of
my function with the same arguments. It must be something I set
without noticing. I cannot get numerical results at all.
In another instance, I have a summation of about 1000 terms defined as
a function of 3 arguments. When I use numerical arguments, instead of
Mathematica calculating a numerical result it generates a symbolic
output with all 1000 terms. Even if a try something very simple such
the output is
Could anyone give me a clue on this?
