A continuous drawing can be made as follows: let F, F' be the foci of
the hyperbola. Take a ruler, say of length m, with end points Q and R.
Attach one end of a string of length m - 2c to R and the other end to F.
Pin the extreme Q of the ruler to F', so that the ruler can pivot around F'.
Now tighten the string with the tip of a sharp pencil, touching the rule
at the same time say at a point P.
