Hi Guys,(adsbygoogle = window.adsbygoogle || []).push({});

Is there any whay I can use the following theorem to approximate the value of e^x at x=0?

[tex] f(x) = f(a) + f'(a)(x - a) + \frac{f''(a)}{2!}(x - a)^2 + ... [/tex]

If the above function is not used for approximation, then what is it used to do?

Thanks heaps
