## Integrals

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

### Integrals

I'm assuming we have to know the concept behind the integral equations (for example the reversible isothermal reaction), but will we need to know how to use it in mathematical practice?

As long as you understand the concept you're good. I think that's why Dr. Lavelle purposely leaves out homework problems denoted with the calculus symbol.

Yeah, I don't think deriving formulas are a requirement of this class, although it definitely helps you understand the concepts better and in the case you that you don't have equations in front of you, you can always get from place to place by deriving formulas.

### Re: Integrals

Calculus is probably not required but its a good idea to understand the conceptual backing behind the formulas. That would include the calculus derivations.
