I cant see if what you have written is right because I had no idea modulus was involved but I have just been playing around with some linear interpolation and from what I can see:
If the curve is and the limits are and then the first approximation of the root, is given by:
The way I got to this was from thinking about what linear interpolation actually is.
First, you take a curve and find an interval which has a root in it, say
Then draw a straight line from one end of the interval to the other i.e. join the points and
Finally work out where this straight line crosses the x axis and bingo, you have your approximation.Last edited by The Muon; 09-11-2008 at 23:07.
