I have a set of X and Y data, degrees of rotation and lift on a camshaft. The
X (degree data) is in increments of 10 degrees. I want to generate the X data
in 1 degree increments. I can generate a curve for the data but is there any
way the that Excell can analyse the data and generate an expression for the
curve so that I can then input the X data in increments of 1 and generate the
corrospond (new) Y data.
