The Taylor series expansion for a function f(x) about the point x = a is given by:

So in your case,

and

The process is just a matter of starting with the first term in the above series, inserting your function evaluated at , and doing any necessary derivatives, etc, to see if it vanishes or not. Then proceed to the next term, and so on, until you have three nonvanishing terms. - Feb 5th 2009, 04:45 PMskeeter
