The excel file, ProjectileData, has three columns of data: time, distance, and height. ... So use the curve fitting tool to fit a 2nd order polynomial (quadratic) to the height data. Display the equation for the fitted polynomial on your graph with 5 digits behind the decimal point. Then copy and paste your plot in …

Fitting an nth degree polynomial to a table of (x,y) points. If the number of data points is m, then n must be m-1 or less, and greater than 0. p=polyfit(x,y,n) Fitting to functions other than polynomials is done by rewriting the function in terms of a straight line, for instance by taking the log of both sides, etc. b.

The line of best fit can be added by hand (a flexible curve will be useful in this application) or with technology. In our experience, adding a trend line in Excel was not as effective as fitting the curve using sliders in Fathom or GSP. The data set should stimulate a rich discussion as to which curve of best fit is most appropriate.

1. Start by fitting the best Excel trendline (don’t forget to record its equation and its R2) to a scatterplot of the data set. 2. Now try fitting your own shifted and scaled basic function on top of the scatterplot and the best-fit trendline, comparing your computed R2 to the R2 of the trendline. 3.

Polynomial Curve Fitting. Add a third worksheet to your “Last,_First_Regress” file, naming it “Polynomial Regression.” Enter the data set on this page into the spreadsheet. (see sample_b.xls on the ENGR-1122 webpage). Fit a linear equation to the data (Yest1=a1x + b1). Fit a second order equation to the data (Yest2=a2x2 + b2x +c2).

Some students assume this curve is some kind of quadratic, cubic or other polynomial curve (especially when they find a polynomial fitting function in excel, or if they have previously studied such curves in class). If so, the teacher may wish to discuss the nature of exponential decay and point out how it is a different beast from a polynomial ...
