NettetTo estimate a value beyond the data shown, extend the graph scale and line of best fit to include the desired point, and then estimate the value of the other coordinate. The equation for a line of best fit is: y=m (x)+b y = m(x)+b, where (x,y) (x,y) represents … NettetExact numerical schemes have previously been obtained for some linear retarded delay differential equations and systems. Those schemes were derived from explicit expressions of the exact solutions, and were expressed in the form of perturbed difference systems, involving the values at previous delay intervals.
