Homework Statement
Show that the function defined by
(stepwise)
f(x)= e^(-1/x^2) if x =/ 0
= 0 if x=0
is NOT equal to its Maclauren series.
Then graph the function and comment on its behavior near the origin.
The Attempt at a Solution
Well, I honestly don't know how to prove this. I graphed it and noticed that as it approaches the origin, it concaves up, so f''(x)>0 at (0,0). Am I supposed to first u-substitute in order to differentiate the e^(-1/x^2)?
