Fig. 2. (Color online) (a) The error area in N2 units is ΔA (for F1+2) = 0.1 × 0.1 = 0.01 in the rectangular coordinate system in F1+2 for Exercise 1-1. (b) The error area in N2 units in the polar coordinate system is ΔA (for F1+2) = dr × rdθ = 0.1 × 30.4 × 0.1° × π180° = 0.005, which is half of that in the rectangular coordinate system.
