#### Propagation of Error with Single and Multiple Independent Variables

Summary Often it is necessary to calculate the uncertainty of derived quantities. This procedure and convention is called propagation of error. Calculating the propagation of error formula requires knowing how to take derivatives/ We give the propagation of error formulas for a single variable and multiple independent variable functions. We list some common error propagation…

#### Reporting Measurements and Uncertainties, Significant Digits, and Rounding

Summary In this lesson, we talk about the number of significant digits used to report measurements and uncertainties. There are conventional rules for the number of significant digits in a number. Experts find that the actual number of significant digits in a measurement is a function of how many significant digits in the uncertainty are…
