Exercises. Answers go in comments.

**Marry, sir.** Find all the typos.

**Moreover.** Convince a skeptic that problem **1** or one much like it is worth learning how to do (and belongs on a Calc I final) even if they know . Hint: even a god-damn *computer* knows that; this is a course for college credit.

**Secondarily.** Explain why one does not go on, “Harvard Calculus” style, to require discussions about *graphs* (without calculations)… I thought this was a course for college credit. For extra credit, justify the *lack* of an “epsilon-delta” proof on this test.

**Sixth and lastly.** Were notations for differentiation () just tossed around at *random* to *confuse* everyone? Or what? Justify your conclusions.

**Thirdly.** How in the name of the nameless name is it even *remotely possible* that after using TeX for seventeen freaking years, Vlorbik doesn’t know how to typeset those limits properly? For that matter, why didn’t he just *scan* last year’s test and *upload* the S.O.B.? How can one *survive* without being able to work the most basic *tools*?

Explain why, despite having been present on two or more occasions when Vlorbik explained how to do the tangent line problem on the calculator with no calculus whatsoever, students will blank out on problem **5**. No, that’s easy. Explain why they think we made up a whole new symbol for the natural log when we really meant the reciprocal function… now *that’s* a mystery. And why should it be hard to recognize a *constant* function, for hecksake? What’s *up* with these people who haven’t learned calculus yet? Why don’t they *get* it?

**And to conclude.** Any questions?
