I am attaching my file. Many of you have given great help on how to get dynamic Maple activities working. My question again is along those lines. I have created a parabola with sliders a,h, and k. What I am trying to do is have a button that says show vertex on the equation . However, when I connect the button with Plot3, I plot the the vertex in a new window. Here is the most successful code I used:
So I do get the point I want (h,k), but the point is not on the function itself. I have tried muliple maple commands with no luck. I am wonder how I can get the point (h,k) to be on the function when I hit the "show vertex" button.
Thank you for you time,
