For more information,refer to ?CurveFitting.Refining PlotsMaple uses an adaptive plotting algorithm. It calculates the value of thefunction or expression at a modest number of approximately equidistantpoints in the specified plotting interval. Maple then computes more pointswithin the subintervals that have a large amount of fluctuation. Occasionally,this adaptive algorithm does not produce a satisfactory plot.> plot(sum((-1)^(i)*abs(x-i/10), i=0..50), x=-1..6);3.43.232.82.6–1 0 1 2 3 4 5 6xTo refine this plot, you can indicate that Maple should compute morepoints.> plot(sum((-1)^(i)*abs(x-i/10), i=0..50), x=-1..6,> numpoints=500);
