comment What property of certain regular polygons allows them to be faces of the Platonic Solids?
The definition of "Platonic solid" requires that the faces are identical regular polygons, but apparently you're looking for some other more general definition that allows irregular polygonal faces. Why is it that you're not counting the triangular bipyramid which doesn't have regular faces? Here's a picture: upload.wikimedia.org/wikipedia/en/thumb/f/f7/…

comment Intuitive understanding of the derivatives of $\sin x$ and $\cos x$
I feel like maybe this should be a question asking if anyone knows of an intuitive explanation and you should write the second part of your answer as an answer. (See meta.stackexchange.com/questions/17463).
