Derivation

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

Derivation

are we going to have to derive or integrate the 1st or 2nd order for test 3 or the final?

Re: Derivation

I believe that Dr. Lavelle said that we will not have to derive equations/formulas in general for tests. However, knowing the derivation is helpful not only for a conceptual grasp of how the equation was arrived at from previous understandings but also in case the equation is not provided.

Re: Derivation

He probably won't but there's always a small chance that he might incorporate it in a question.

Re: Derivation

I don't think we will be asked to directly derive the equations. However, understanding the derivations may help with the conceptual questions on Test 3.

Re: Derivation

It is possible that he asks for the derivations, but knowing how to utilize and understand the equations is much more important.

Re: Derivation

My TA said we won't have to do any derivations on the test, but knowing them does help increase understanding of the concepts

Re: Derivation

My TA said that if he asks us to derive on the exam, then it would be simple equations that we have gone over many times.

Re: Derivation

I will probably learn them regardless. I think knowing the derivations helps to better understand what the equations mean, where they came from, and overall helps keep the equations straight in my head.

Re: Derivation

No. My TA stated that this won't be necessary. However, Dr. Lavelle has spoken on how it helps to know how to derive each formula, as it demonstrates a deeper understanding of the concepts.
