Math question

I am not saying I am sure, but even after your reply, I still believe I
was right. I am 99% sure that the result is exactly +1.0 no matter what
you do....

sorry, but as far as I know, this expression has NO certain value. It
has a value between  -1 and 1 depending on the row of x's that you
choose. Guess you should ask someone in a group dealing with math
problems to get an answer for sure ...

What do you mean by 'row of Xs' ?  You can either approach
0 from the positive side or the negative side, and for
this particular equation it doesn't matter.  sin(x)/x is considered
to approach 1, since it can't ever actually reach it (because
of the division by zero as you get infinitely close).
