A function may be
continuous, but still not
differentiable.


Here are the haikus that the Math 1151-001 students have permitted me to share.

L'Hospital's Rule
How to find limits with ease
Wish I learned it first.

Epsilon, delta
Driving me to my limits
Silly Greek letters.

Delta, epsilon
It's just like finding limits
But much, much harder.

Approximations
Not exact. Not precise. But
close enough. I guess.

L'Hospital showed me
a cool way to solve limits
Use derivatives
