## Integrating

$\frac{d[R]}{dt}=-k[R]; \ln [R]=-kt + \ln [R]_{0}; t_{\frac{1}{2}}=\frac{0.693}{k}$

### Integrating

Are we going to have to know how to integrate the equations with derivatives in them?

### Re: Integrating

It might be helpful to know where the equations come from, but I believe the final/core equation will be provided on the equation sheet. Unless another equation is taught to us that requires the use of derivatives/integrations later on, I don't think it's absolutely necessary to learn these concepts. However, Dr. Lavelle emphasized calculus in this unit, so it may be helpful to at least understand where the equation is derived from. He also posted a review of these topics with a chemistry emphasis on the Chem 14B website!

### Re: Integrating

You should know how to get from the first equation to the last equation. Both of these will be given, but you should know how the last equation is derived from the first equation.
