Hello everyone. I Very Excite to be here : D!
Ok, so I was reading on taylor polynomials for several variables and came across the following on wikipedia:
<math>T(\mathbf{x}) = f(\mathbf{a}) + \mathrm{D} f(\mathbf{a})^T (\mathbf{x} - \mathbf{a}) + \frac{1}{2!} (\mathbf{x} - \mathbf{a})^T \mathrm{D}^2 f(\mathbf{a}) (\mathbf{x} - \mathbf{a}) + \cdots\!
</math>
Or, please follow the link:
http://en.wikipedia.org/wiki/Taylor_series#Taylor_series_in_several_variables
*it is the second to last expression in that section.
What do they mean by that "T" on top of the matrices? what does it tell us to do?
Thanks.
