Why won't my sinusoidal code display a plot?

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

clc; clear all ;
v = sqrt(2);
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);
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
In Vs,Vc,Vl you are taking only one time step t. It should be a vector, time

Thank you! I didn't realize I was doing that, these late night pulls are killing me but I appreciate your rapid reply!
