Plot the following analog signals in MATLAB Plzz Help?

Plot the following analog signals in MATLAB(30)
T= 0:0.001:5
1. x(t) = sin(t)
2. x(t) = u(t-1) + delta(t-2)
3. x(t) = u(t-1) -u(t-3)
Plot the following discrete signals in MATLAB(30)
N= -5:5
1. x[n] = u[n-2]+u[n+1]
2. x[n] = u[n+1]-u[n-3]
3. x[n] = 4*u[n-1]-2*u[n]

Check the system (30)
X[n] = (0.8) ^n * u[n]
1. memoryless?
2. Stable?
3. Causal?

Hint: (Assuming T and t are the same):

t = 0:0.001:5
x = sin(t);
plot(t, x, 'b-', 'LineWidth', 2);
grid on;
xlabel('t', 'FontSize', 20);
ylabel('x', 'FontSize', 20);

For the ones that deal with n and n-1, you'll need a for loop. Look up "for" in the help

I assume you can finish it now. Post your code with any problems. I would also assume that by N they also mean n. MATLAB is case sensitive, and the problem writers don't seem to know this fact.
