hello i have an iteration table for a maclaurin series, can anyone tell me what's the coding to make a table like this?

There are several ways to calculate a series in MATLAB. From your question, you appear to be a beginner, so I will show an intuitive way using for-loop.

term_n = @(x,n) x^n./factorial(n); % formula for n-th term of series
N = 10; % total number of terms we are going to calculate
result = zeros(1,N+1); % initializng a array to save the partial sums
eplison_t = zeros(1,N+1);
eplison_a = zeros(1,N+1);

x = 1/2; % value of x to use in this calculation
result(1) = term_n(x,0); % calculate first term of the series at n=0
eplison_t(1) = (exp(x) - result(1))/exp(x);
for n=1:N % terms n=1,2,...,N
    result(n+1) = result(n) + term_n(x,n); % current partial sum is the addition of last partial sum and the value of n-th term
    eplison_t(n+1) = (exp(x) - result(n+1))/exp(x);
    eplison_a(n+1) = (result(n+1)-result(n))/result(n+1);
end

eplison_t = 100*eplison_t;
eplison_a = 100*eplison_a;

t = table(result', eplison_t', eplison_a');
disp(t)

Result

thank you so much for your reply, really appreciate it

[Ameer Hamza]

Glad to be of help.

i was wondering, you didn't input the coding for the formula of epsilon s. can you tell me why??

[Ameer Hamza]

It was not on the table, so I didn't notice it. You can follow the same method to add it to the code.
