A Well-Chosen Exam Question

For a week now, there has been a list of exam topics on the course webpage.

During the review session on Friday, I used the definition of the derivative to find d/dx(x^{1/3}). I told my students that they wouldn't be asked to one that complicated on the exam, but that they should be able to do \sqrt{x}. I mentioned that \sqrt{x} was even an example in the text.

I have no pity for the (many) students who were unable to use the definition of the derivative to find d/dx(\sqrt{x}). The only comment I'm writing is "See p. 158."
