Example sine wave

Vm = 25;
w = 200*pi;
phi = 30*pi/180;
f = w/(2*pi);
fprintf('angular frequency %g\n',w);
fprintf('frequency %g Hz\n',f);
fprintf('period %g msec\n',1000/f);
fprintf('peak value %g V\n',Vm);
fprintf('rms value %g V\n',Vm/sqrt(2));

angular frequency 628.319
frequency 100 Hz
period 10 msec
peak value 25 V
rms value 17.6777 V
