Unformatted text preview: in a calculated quantity we use calculus. If we measure a quantity x and wish to use it to compute a value f ( x ) we can use the fact that the derivative df ( x ) dx gives the relationship between a change δx , and the corresponding change δf , according to δf = df ( x ) dx δx , so letting δx be the uncertainty in the measured quantity x , δf is the uncertainty in the calculated quantity f ( x ). Appendix B described how the uncertainty in a value calculated from several measured quantities is determined. 4...
