Re: Tweede graads vergelijkingen in Excel

in Excel is ook de optie:

=LINEST(y's,x's^{1,2},true,true) 2nd (quad) order
=LINEST(y's,x's,true,true) linear

met de index formule kan de waarde gezocht worden

Bedankt voor de tip!

"The LINEST function calculates the statistics for a line by using the "least squares" method to calculate a straight line that best fits your data, and then returns an array that describes the line.

You can also combine LINEST with other functions to calculate the statistics for other types of models that are linear in the unknown parameters, including polynomial, logarithmic, exponential, and power series."
