F ( x) To calculate the derivative f ( x) of f ( x) = (4 - x) /(3 + x) . (b) The radius of a circular disk is given as 24cm with a maximum error in measurement of 0.2cm. (i) (ii) (c) Use differentials to estimate the maximum error in the calculated area of the disk. What is the percentage error of this calculation?
