One of my students once told me that his brother, an engineer, said that
gradients were used in some engineering fields.

Thanks for the ideas for construction projects for the volumes by cross
sections. I plan to use them this year.

Also, re the question about grading AP exams and whether or not the
intersect button is ok to use. It is (as long as you explain why you are
doing it), but some students lost points because they used the trace
button, which was not as accurate.
