Hi. I would like to draw your attention to the following drawn in the application (Geometry and Function) incomplete graphs of logarithmic functions LN(x) and LOG(x). One arm of these functions is long, continuous and thus correctly drawn. The second arm is very short, too short. The essence of the problem is that the graph of each function should be legible, clear and understandable. This is not the case here. However, it draws LN(x) and LOG(x) charts very well, the Advanced Graphing application. The arms of these functions are long, drawn well. Please see this on the attached HP PRIME screenshots.
