$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Math skills

This unit includes how to derive an equation for the work of an isothermal, reversible expansion and it includes integration. Should we be reviewing our calculus skills and techniques for these units and future chem 14B units? Or is the derivation trivial and we just need to understand the derived formulas?

I doubt we will need to use much calculus for Chem 14B, but if we do it will probably only be basic integration and nothing very complicated. If there are special integration or calculus skills that we need to use for problems I am sure Dr. Lavelle will go through it thoroughly in lecture.

Yeah, and if anything you should practice the problems with the derivatives to see how challenging it would be at your current knowledge.
