One side of a right triangle is known to be 21 cm exactly. The angle opposite to this side is measured to be 60°, with a possible error of +0.1°. Round your answers to three decimal places. (a) Use differentials to estimate the errors in the adjacent side and the hypotenuse. Propagated error in the adjacent side: + i cm Propagated error in the hypotenuse: + i cm (b) Estimate the percentage errors in the adjacent side and hypotenuse. Percentage error in the adjacent side: ± i Percentage error in the hypotenuse: ± i %
