Sig Figs
Use the same methods we developed in class. Generally speaking 2 - 4 sig figs work fine as long as you wait until the end of your calculations to round up or down.


Understanding and interpreting the questions on the AP Exam is absolutely critical. To wit:

Calculate: Show all your work including units
Derive: Begining with known formulas, show in a step-by-step manner how you would determine the required expression
Graph: Make a pretty graph, be sure to include the title, x and y axis labels and any important parts of the graph (eg slope is increasing, decreasing or zero)
Sketch: Quick and dirty graph that shows you understand the basic trend of the data. X & Y axis labels are not required (but are a good idea)

There once was a lady named bright

Who Traveled far faster than light

She set out one day

In a relative way

And came back the previous night!
