Yes, it is possible. There are a variety of techinques that can be used. For example, you could use Interpolation to find an interpolating polynomial of the desired order. Or you could use Series to find a power series the converges to the function. And then there are various addtional packages such as NumercialMath`SplineFit` that can be used to find an approximating function. The choice of which technique to use depends on what you want to accomplish. If you need more specific suggestions it is up to you to provide details of what you want to accomplish. -- To reply via email subtract one hundred and four
