Topic: How do I draw Dotted/Broken vertical lines?
I want to draw a dotted vertical line.
For example, I enter the relation x = 5. It only shows up as a solid line, not dotted or broken.
Additionally, I need to draw a box (dotted sides) in my animation to draw the asymptotes for my hyperbola.
As a note, I love your program. I use it in class for demonstrations. I have my students use it to create pictures using equations/inequalities.
Finally, is there a place/forum where users of GRAPH share their graphs/animations?
