Consider the time history of pressure changes in a manifold carrying a fluid, extracted from an experimental test, tabulated as below: t(s) 0.15 0.65 1.25 1.75 1.95 2.05 p(pa) -1.0113 -1.2146 -1.5043 3.8111 16.5889 30.8242 determine the pressure change with respect to time (dp/dt) at t = 1.25 s using: (a) forward finite-divided difference (b) backward finite-divided difference, and (c) centered finite-divided difference. tabulate your results to compare them.
