When I run the code, an empty plot displays. How do I make it display my sinusoids?

v = sqrt(2);
  f = 2500;
  t = 1/f;
  time = [0:0.00001:2*t];
  w = 2 * pi *f;
  Vs = sin(w.*t);
  Vc = v./2 *sin(w.*t+45);
  Vl = v./2 * sin(2*t-45);
  plot(time,Vs)
  hold on
  plot(time,Vc)
  hold on
  plot(time,Vl)
  hold off
  legend('Vs','Vc','Vl')
  title('Plot for Question 5')
  xlabel('Seconds')
  ylabel('Volts')
  grid on

f = 2500;
t = 1/f;
time = [0:0.00001:2*t];
w = 2 * pi *f;
Vs = sin(w.*time);
Vc = v./2 *sin(w.*time+45);
Vl = v./2 * sin(2*time-45);
