Given:
Discreet signal: sin((2𝜋f/fs)∙n∙T)for n=0,1,2,..
f=26;
fs=200;
n=2;
dt=0.005;
t=n*dt;
Required:
T==> I have to pick an integer value of T>1 such that sin((2𝜋f/fs)∙n∙T)is a periodic discrete signal.
How to graph periodic continuous signal sin(2𝜋ft) and periodic discrete signal sin((2𝜋f/fs)∙n∙T)

You can use plot to graph continuous signal, and stem to graph discrete signal.
For example:
t = 0:6e-2:1;
signal = sin(2*pi*t);
subplot(2,1,1)
stem(t,signal)
subplot(2,1,2)
plot(t,signal)
