Graphing Two Or More Equations
I noticed that the area to the left of the Y1= et.al has changed and I can no longer highlight two or more y-vars. I already tried the manual suggestions and reset. How do I restore the ability to highlight two or more equations under y= so that two or more equations can be graphed in the same window?
