Arrgh! The last sentence is missing a line. It should read: "From this,
you may obtain an *approximation* that's analytic everywhere: just
replace Infinity with a suitably large odd integer, depending on the
bandwidth of your voltage source."
Silly me, I used the keyword "From" to start a line, which seems to have
confused something along the forwarding chain (even though it showed up
in my outgoing log escaped with ">"). Isn't SMTP/NNTP great? :-(
