(a) Consider a function f(x, y). The small changes in x, and y are represented by Ax, and Ay respectively. The resulting change in f is given by af Af= af Әх ду Ar+ -Ay. (i) How should this expression be modified if Az, and Ay represent uncertainties in inde- pendent measurements? (ii) Use this modified expression to find the fractional uncertainty in f., if the function f is given by f = aryb, [10 Marks] where a and b are known constants.
