The figure shows a curve with a tangent line segment of length 1
that sweeps around it, forming a new curve that is usually outside the old one. Prove Holditch’s theorem, which states that the new curve’s area differs from the old one’s by 
. (This is an example of a result that is much more difficult to prove
without making use of infinitesimals.)
