Polynomial interpolation in excel

WebIn theory the Weistestrass approximation theorem says continuous functions on the interval can be uniformly approximated by polynomials. Using the argument above it makes sense that 2-variable polynomials are dense in continuous functions on the square. This is a special case of the Stone-Weierstrass Theorem: $$ \overline{ \mathbb{R}[x,y]} = … WebExcel charts are a convenient way to fit a curve to experimental data. First, create a scatter chart. Then right click on the data series and select “Add Trendline…”. In the Format Trendline pane, select the options to Display Equation on chart and Display R-Squared value on chart.
