Problem 2. An experiment with an RC-circuit shown in the VR(I) figure is conducted. The experiment starts by closing the switch S and measuring the resistor voltages Vg every 4 seconds. The data R (5 MO) measured in the experiment is: t(s) 2 10 14 18 22 6 Vr(V) 9.75 6.6 4.54 2.85 2.15 1.46 (a) Obtain the resistor voltage at t = 7.35s using the 2″nd. and 3rd-order Newton's Interpolation formulation. Order the points so that they are as close to and as centered about the unknown as possible. Calculate the value of the remainder for the 2″d-order polynomial in two ways.
