Homework Help: Error analysis

  1. Oct 28, 2007 #1
    1. The problem statement, all variables and given/known data
    Hello, i'm doing an error analysis problem and i'm not sure how to compute this.

    What is 1.23 +/- 0.03 + pi

    2. Relevant equations

    I know the equation for the error of two additions. Error = sqrt of ( error in x ^2 + error in y ^ 2 )

    3. The attempt at a solution
    But i'm not sure if theres error in pi, so basically i just did 1.23 + pi + / - 0.03

    i am not sure if this is right can someone clarify

    It really depends on the context, but you should be right. Essentially what you are saying is that the error in pi is zero, since pi is a known constant. So the adding in quadrature formula would give you just the original error.
