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. WebSep 28, 2014 · Polynomial interpolation is a different thing; you can do a polynomial interpolation (i.e., estimating values between the tabulated values) without doing a regression.
