## equation derivations

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

### equation derivations

Are we ever going to be asked to replicate the derivation of an equation on an exam? Some of the derivations in this section were confusing, and if I can just memorize the equation I need and get full points, it would be really helpful for me.

No, he mentioned at least on the midterm that there will not be any derivations so I think that same principle applies to the final.

I don't think so but I would maybe ask him or a TA. Because we go over derivations a lot but we don't seem to do them on any homework problems or tests.

I don't think so, I think he just wants you to "know" them but they won't appear on an exam.

I don't think so, but maybe you can ask him during office hours. I feel like Dr. Lavelle cares more about using the equation correctly than just memorizing an equation.
