There are a number of items I could submit here:
The exploration of Pascals' triangle and its relationship with Sierpinski
triangles - I am not submitting this now as I would still like to develop
that a great deal.
I will rather submit an exploration I did using GSP to solve a problem posed
in my MAT722 class - I believe that this is an example of how I actually
used the work done in this course to address real problems posed in another
course. That is I used the tools of this course to solve an actual problem
with which I was struggling (click
