This is a series of applets drawn from the website mathMINDhabits [sites.google.com/site/mathmindhabits]
that is designed for teachers of mathematics who want to deepen their understanding of the mathematics they teach
and that their students are expected to learn.

There are operations such as addition, multiplication and differentiation on functions viewed as objects. Functions are objects that can be transformed by such transformations as translation, dilation and reflection.
