### Quiz Question

So from what I've looked at in the practice quizzes and the book questions we don't have to know how to derive each formula correct? But why then do we spend so much time in class covering it ?

### Re: Quiz Question

We don't necessarily have to know how to derive all the formulas, but we need to know how to use them and when they are used. Dr. Lavelle spends time deriving them to show us where they come from and what they mean in the context of different problems.
