Hello, Firstly, thank you for your reply. However, I would like some further explanation please. If I understand, but I'm not sure at all, calculating (xmax-xmin) / 10 gives the number of points to draw the curve. However, in my example, xmax = 4 and xmin = -2, so (xmax-xmin) / 10 = 0.6. My question is : how do you find the value in 1000 ?
