I need to enter temperatures in documents and there are three three ways I
can do this:
1. \circ (amsmath)
2. \degree (gensymb)
3. \textdegree (textcomp)
I've tried all three, including putting all of 'em in the same
\userpackage{} command in the preamble.
Regardless, each throws an error when compiling using pdflatex.
What have I done incorrectly?
