Hi everyone, I have stored values of a sinusoidal signal in a file.dat, i worked with a Frequency of sampling which is worth 8000hz,now i want to plot my signal from the file.dat in matlab but i don't know how, can you help me please!?

I would do it this way:
fidi = fopen('file.dat', 'rt'); % Open File For Reading Text
Dc = textscan(fidi, '%f', 'CollectOutput',true); % Change ‘textscan’ Arguments To Match Your File
D = cell2mat(D); % Create Numeric Array
Fs = 8E+3; % Sampling Frequency (cycles/time unit)
Ts = 1/Ts; % Sampling Interval (time unit/cycle)
t = linspace(0, 1, length(D))*Ts; % Time Vector (Delete If You Saved Your Time Vector In Your File)
figure(1)
plot(t, D) % Plot Your Data
grid
Note — This is quite obviously UNTESTED CODE. A version of it should work. You will have to experiment with it with your data.
See the documentation for the various functions to understand how to use them, and how they work.

this how it will work
first you will have to import the dat file to matlab using import command
then assign that to a variable
for example import file.dat
d=file
then use that data and sub in to yoru sin equation
y = sin(d()*t)
whatever your t value is
then plot the signals
