Design the circuit shown in Figure DP 9-1 so that vc t 0:8 e2t A1 cos 4t A2 sin 4t V for t > 0 Determine the values of the unspecified constants A1 and A2. Hint: The circuit is underdamped, the damped resonant frequency is 4 rad/sec, and the damping coefficient is 2.

3.3 INFERENCE FOR POPULATION VARIANCE 1) We can calculate the estimated population variancewith 2) also note that this is true: 2 *where X is representative of the chi square distribution with...
