1..Consider weighed quantities T = 4,71g, T = 3,98g and T, = 4,12g described by the equation T = In (27). If allowable deviations from the weighed values are to be within 1%, 3% and 2% respectively, determine the maximum percentage error in the calculation of T. (8) 1.2. The data in the table depicts the melting point of a alloy of lead and zinc where I is the temperature in degrees Celsius (C) and p is the percentage of lead in the alloy. 1.2.1. Construct a divided difference scheme for the data (4) 1.2.2. Use the divided difference polynomial to estimate the melting point of the alloy containing 84 and 92 percent lead respectively (5) 24 26 40 50 60 70 80 90 P T (C) 180 204 226 250 276 304
