Evidently we weren't the brightest class in recent memory, because she decided to review some single-variable calc during a review session. Here's how she helped us remember the derivatives of the exponential and natural logarithmic functions.
"e^x is like a strong child. You hit it [with a derivative] and nothing happens."

"ln x is like a weak child. You hit it and it dies."

I think there was audible consternation. But we remembered.

From either that review session or another she also referred to ln(x) as a scared child that, when hit (with a differential operator), would go under the table.
She was all kinds of quirky, and al kinds of brilliant. I really enjoyed her lectures (and the way she said 'h').
She would also say "dot" (for dot products) like she had just stepped on a rusty nail. It woke up anyone who happened to be nodding off in lecture.
