If you have a function you can use the CALC menu to find a value, find a zero of the function or find a maximum or a minimum. What if you only have equally
spaced data points available without any functions? It is still possible to use
only that data to obtain a value, find a zero of the function or find a maximum or a minimum.
The process of doing this is referred to as “Interpolation”. In general, the data can be in the form of a table, however, it is not required that the data come from a book. It can also have been generated by your calculator or a computer programmed with a set of equations to complex to be entered into your calculator. You can even obtain the data points from an experiment in a laboratory.
INTRPOL8 will find all of these and it can do more. It can find the number that is exactly halfway in a set of numbers and it can generate a difference table of your data (up to 5 points). It also can create a function that will reproduce the data you supplied and it can plot out the data. And it does all of this usually using only 3 or 5 data points.
