Create a time vector, sine wave, 5 periods, 1 kHz, amplitude 2 volts in 5 x 1024 samples (time axis) as well as 5 periods in 4096 samples

t=[0:1:1024]; A= 2; f=1000; fs=5;
x=sin(2*pi*f/fs*t);
plot(t,x)
I am new so, I am not sure if it is correct with the context of the question?

You're very close:
freq=1000;%1 kHz
t=linspace(0,5,1024)/freq;%from 0 to 5 periods in 1024 steps
A=2;%amplitude
x=A*sin(freq*t*2*pi);
plot(t,x)
I don't really see how more samples will change things, but you can just change the linspace parameters.
BTW, for next time: have a read here and here. It will greatly improve your chances of getting an answer.

x=0:3.14/100:2*3.14;
y=sin(x);
plot(x,y);
title('A Plot of Sine Curve');xlabel ('x-axis');
ylabel ('y-axis');
