Machinists
Description: Machinists make metal parts using lathes, drill presses, and milling machines. They often make specialized parts or one-of-a-kind items for companies that produce everything from cars to computers. Most work in machine shops and wear safety glasses and earplugs. Because of the machinery they use and the coolants and lubricants for the machine, this can be a dangerous job.

Comments:
Add machine tool programming/tool & die to what occupations use calculus. I need to do slope of a curve at a certain point at times. And I'd be lost in endless high school math without analytic geometry to do intersections and corner breaks.
