Interpotating a curve

Is there anyone out there who can explain this to me in terms I'm likely to understand?
It's really doing my nut in.

i would have a try if i could pronounce the word.

or is it an error based on the Devons Daddy spell checker software.

Interpolating a curve means joining up the dots.

Interpolating a curve is where you hava a collection of points and you fit the best curve possible in order to know the function on the given range. See the "Newton-Gregory forward difference interpolation formula". Its a piece of piss.

thank you all for that advice, but how the hell do you use the flaming Newton-thingumy formaula to do it?

You have to make up a table of differences between successive values, and the differences between the differences and so on until the difference is constant. That tells you the order of polynomial best suits the points. After that I canna quite remember...
