Consider the AC circuit below. We will assume that the circuit is in steady-state. Thus, the voltage at nodes 1 and 2 are given by v_{1} = V_{S} coswt and v_{2} = V_{R}cos (wt + q ) where V_{S} is the voltage of the source, w is the frequency (in radians per second), and t is time. V_{R} is the magnitude of the voltage drop across the resistor, and q is its phase.
You are to write a program to determine V_{R} for different values of w. You will need two laws of electricity to solve this problem. The first is Ohm's Law, which states v_{2} = iR where i is the current in the circuit, oriented clockwise. The second is i = C d/dt (v_{1}-v_{2}) which relates the current to the voltage on either side of the capacitor. "d/dt"indicates the derivative with respect to t.

The input will consist of one or more lines. The first line contains three real numbers and a non-negative integer. The real numbers are V_{S}, R, and C, in that order. The integer, n, is the number of test cases. The following n lines of the input will have one real number per line. Each of these numbers is the angular frequency, w.
