Using the first three terms of the Taylor series of - f(x,y) about (a,b), we can write f(x,y)-f(a,b)(-a) (vb) By measurement, -20 with maximum absolute error 0.03, and y 16 with maximum absolute error 0.02. That is, -20 ≤ 0.03 and ly-16 ≤ 0.02. Estimate the maximum possible error in the computation of z. Enter your answer to 2 decimal places in the box below
