Propogating error

  1. Jan 25, 2010 #1
    I am running a test where I start by preforming a calibration to fit the following linear line

    V= a * X + b

    where: X is Displacement, and V is Voltage reading.

    Then, I acquire my data where I measure V and find X based on X = V/a ( the b drops down ), and find an angle Theta = X/f such that Theta = V/(a*f)

    My questions is:

    If I know that the uncertainty of the slope 'a' is

    where

    How can I find the uncertainty of Theta?


    Thank you
