Question: Buttons and Graphs

December 20 2013 nicholasfbennett 30


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 y=a(x-h)^2+k. 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,
