Dear Mathgroup, I would like to plot the integral of, (Sech[betaN * x^n])^2 , where beatN=121.643 and n=2 say. I have started by making a table of x values as np=100; x1 = Table[(-0.5 + ((i -1)/(np-1)), {i,1,np}]; x2 = t1^n; x3 = (Sech[betaN * x^n])^2; I have tried NIntegrate but of course that just returns the total area of x3. Any help would be much appreciated. Yas
