WebIn other words, interpolate the column E values corresponding to the column F values. For example, A3=3 and B3=7. In this case, F7=7 and E7=3 because B already included the integer 7 and has a matching value in column A. However, F8=8, which is an intermediate value not contained in column B. So E8 will lie between 3 and 4, based on the ... WebI needed to understand how to define a polynom functional from 3 presented points.

WebExample #1 – Using Simple Mathematics Formula. Let us say we have a simple dataset of two known x and y values, and we wish to interpolate a value (i.e. find the corresponding y value for the x value) as follows: So the simple formula that is used to interpolate this value is: y= y 1 + (x – x 1) *. Here x=22.5.
