%X We show that the maximum or minimum impedance of a special parallel RLC studied in a previous paper can be found analytically, without using calculus. In fact, we show that the maximum or minimum value occurs when the driving frequency   is equal to  o  1/ LC , a fact that was determined graphically in that previous paper. Furthermore, we show that either the maximum or minimum value is given by R     2 2    1 3 ,      where     L C R / / . Also, for the minimum impedance Z R R min        1 2 /3 3 /3,  2 whereas for the maximum impedanceZ R R max        1 2 / .
