This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.
If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.
If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

Actually it is, tommorow is the last day for submission and i dont have enought time .
I've tried to solve it with assistace of youtube and i findout it's useless .

Okay, @eslam yasen
I understand your situation. Go back to the youtube video you watched and then type out the codes (paste them here).
Will see what can be done or improved from the codes you typed out.

You'll be able to do this in 2 hours if you do the 2 hour onramp course here:

Hi,
You can refer the given basic implementation for (a) and can follow similarly for (b) and (c).
%intialise the values of N%
x=[2,30,100,1000];
%some arbitrary values t taken for calc,here 2 values for taken t=0 and t=0.5%
T=[0,0.5];
%initialise the output(y) as 2-D array(4x4) each row corresponds to a t value%
y=zeros(4,4);
%loop for t values%
for t=T
%set row and ind(col) as 1%
ind=1;
row=1;
%loop over all the N values%
for n = x
sum=0;
%calculate the val of func using n & t %
for i = 1:n
multiplier=(-1).^(n+1);
multiplier=multiplier*1/(2*n-1);
output=multiplier*cos((2*n-1)*pi*t);
sum=sum+output;
end
sum=sum*12/pi;
%finally store the value in y%
y(row,ind)=sum;
ind=ind+1;
end
ind=1;
row=row+1;
end
%plot to realise the values for N=[..] over t=0 and t=1/2%
plot(x, y(1,:), x, y(2,:), '.-'), legend('t=0', 't=1/2')
Hope this helps !
