Oh, math-lover most divine,
for you this mathy Valentine --
found when I lookedin a calculus book --
a cardioid is the heart-sign.
Take two equal circles and wind
one round the other -- aligned
with the start-touchpoint tracing
the heart-shape that’s gracing
this limerick Valentine.
Please be mine!
