I have some difficulties with finding the coordinates from contourplot. How would I extract the coordinates from the plot. I can try to use the right click and then choose the "Get coordinates". That is supposed to be working, right? But it seems there are still some errors since when I clicked it is not actually right on the curve. Moreover, I do not only need just a few points, but I do need every single points on the curve. Would you recommend anything to fix this?
