**4th Order Polynomial in Excel -Engineering spreadsheets**

First the data must be entered into an Excel worksheet (click on image to download the file). One way to perform polynomial regression is to fit the appropriate trendline to the data (and there are a number of options in addition to polynomials).... Last week, I posted an article about sigmoid functions and how to use them. Nevertheless, it is hard to guess the parameters for a given problem. So, people use software such as Origin [1] or QtiPlot to fit. Personally, I use Origin/QtiPlot only for plotting and Excel/OO–Calc for evaluation
