I have a tutorial question on Taylor series.
$f(x,y,z) = e^{(\sqrt{x y}+\sqrt{x z}+\sqrt{z y})}$
I managed to get the Taylor series at (1,1,1)
Is it possible to get the expansion at (0,0,0)? Because at (0,0,0) the derivative is 0/0 which is confusing...how do we evaluate 0/0 in Taylor series?
Thanks!
