comment Find the dimensions of a cylindrical can that will minimize the cost of the material
Aha... I had been using D (partial derivative) necessitating the expression of h in terms of r. I see that Dt takes care of this. Thanks again J.M.!

comment Find the dimensions of a cylindrical can that will minimize the cost of the material
@J.M. I'm still curious as to how to solve it with Reduce. I added an answer which takes the approach I was looking for, but uses a rewrite kludge.

@J.M. Wasn't familiar with Minimize... Thanks for the suggestion! However, is there a way to get the answer not in terms of Root?

comment Using implicit differentiation to find a line that is tangent to a curve at a point
Thank you @J.M.. I also decided to explore using a program to solve this sort of problem. I've posted a separate answer illustrating this approach.
