A limerick, expressed as an equation...

[alexpgp]

The following equation, when read aloud, has the same meter and rhyming scheme as a limerick:

Integral zee-squared dee-zee
from 1 to the cube root of 3
times the cosine
of three pi over 9
equals log of the cube root of 'e'.

This curious equation has been around since at least the time I was in engineering school.

The equation is valid, by the way. :^)

Cheers...
