Data analysis: error calculation

  1. Dec 14, 2012 #1
    1. The problem statement, all variables and given/known data
    A=0,078m
    l=2,27m
    relative error of A: 0,01
    relative error of l: 0,005

    What is the error of: arctan(A/l)?

    Can you at least compute the relative error of A/I?
    Do you know how to use Taylor expansions?
