I need to setup a function where MATLAB will take two input values one for angle (x) and one for numeric position (n) and it should return a double floating number which is the approximation of the series where x is in radians. Thank you in advance.

Hi John,
I understand that you want to write a function to find the taylor series of cos(x). Here have attached the following code for your reference.
function result = taylorCos(angle, numTerms)
x = angle;
n = numTerms;
% Initialize the sum and the first term of the series
sum = 1;
term = 1;
% Compute the remaining terms of the series
for k = 1:n
term = (-1)^k * x^(2*k) / factorial(2*k);
sum = sum + term;
end
% Return the result
result = sum;
end
This code defines a MATLAB function called `taylorCos` that calculates the Taylor series expansion of the cosine function. It takes two inputs: `angle`, which represents the angle in radians for which the series is computed, and `numTerms`, which specifies the number of terms in the series.
The output will be the approximation of `cos(angle)` using the Taylor series expansion. Additional information on the Taylor series and how to use MATLAB functions can be found in the provided links.

I hope this resolves your query.
Thanks,
