So, the integral is clearly 2 x 1 = 2 = Min[a,b] not Abs[b-a] >b = 5; a = 3; >Plot[fl[e](fr[e - a] - fr[e]), {e, -5, 5}, PlotStyle -> {Thickness[0.01]}] This plot shows the function to be 0 for e < 0 or e > 3 and 1 otherwise. So, the integral is clearly 3 x 1 = 3 which again is Min[b,a] -- To reply via email subtract one hundred and four
