Error AnalysisHardQuestion 5043

Question

The relative error in the product of two quantities a and b with relative errors δa/a and δb/b is:
  1. A
    δa/a − δb/b
  2. B
    δa/a × δb/b
  3. C
    δa/a + δb/b
    Correct
  4. D
    (δa + δb)/(a × b)

Correct answer

δa/a + δb/b

Explanation

For a product P = ab: δP/P = δa/a + δb/b. Relative errors add for products and quotients.
