Trend-adjusted exponential smoothing, as I understand it, is a method
of forecasting demand. I would appreciate some further information so
that I may better my understanding.

Please include the following information:
* a brief explanation (am I correct?)
* The formula used to forecast demand for the next period in the
series (please enter it as if   you were using Excel, IE using
parentheses appropriately for fractions)
* An example of how the formula works in forecasting demand for a
period, using data of   your choice. Please work through the formula
and show your calculations.

Feel free to ask for clarification if something is unclear.
