8.34 The charge on the capacitor in the RC circuit shown at various times after the switch is closed at time t=0 is given in the following table. The current, I, as a function of time is given by I(t)= d. Determine the current as a function of time by numerically differenti- Vo ating the data. dt (a) Use the user-defined function First DerivUneq that was writ- ten in Problem 8.23. (b) Use the MATLAB built-in function diff. In both parts plot / versus t.
