For example, consider the well known formula y = sin(x) and start Function Plotting (press (F10) (Graph)), set the RAD option (press (MENU) Options Radians), set XMIN= O, XMAX= 10,100, YMIN=-1.2, YMAX= 1.2 and XVAR=X. Now your parameter to play with is the Resolution (F10), the number of points to be calculated for a curve.
As you vary (F10) from 179 to 195 or over, as I did, you can watch how dramatically curves will change their character. You will receive the most beautiful patterns worth studying in a time of leisure and relaxation. In case your boss wanders by: It's all mathematics!

How do you like that N= 189 or 193? Try to plot y = sqrt(x)*sin(x) and see what happens when you change XMAX (F6) and/or F I 0. Find your own formulas.
For those of you interested in theory of mathematics: Because of the wide range of the x-axis values for the y-axis are calculated not from one and only 'hill-and-valley' as usual but are collected 'jumpwise' from 'hills-and-valleys' set widely apart but still following strict mathematical rules and thus not allowing for a smooth connection of all points.
