Question

How can we estimate the error in the product of two quantities?​

Answer 1

Explanation:

When two quantities are multiplied or divided, the relative error in the result is the sum of the relative errors in the multipliers. Z ± ΔZ = (A ± ΔA) (B ± ΔB) = AB ± B ΔA ± A ΔB ± ΔA ΔB. Dividing LHS by Z and RHS by AB we have, 1 ± (ΔZ/Z) = 1 ± (ΔA/A) ± (ΔB/B) ± (ΔA/A)(ΔB/B).

Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic errors are due to identified causes and can, in principle, be eliminated. Errors of this type result in measured values that are consistently too high or consistently too low.
