how to implement the algorithm for approximating Cosine using the Taylor series

The Taylor Series approximation for Cosine with varying values of n from n=0 to n=4 is given. and i have to use two arguments, theta and n where theta is angle in radians and n is the number of terms.

You need to write it. This is your homework, not ours. If we write it for you, then you learn nothing, except how to get someone to do your work for you. And you can surely do some reading online to find the basic algorithm. All you need do then is convert the pseudo-code into MATLAB. And that needs to be your job.

I did try but nothing worked before. I just found out it was because I was using an alternative software for Matlab.

Next time please post what you have tried. Please don’t expect others to write your homework.

turns out it did not work before because I was using an alternative for Matlab. I would like to remove it

The mere fact you were using Octave doens't make this question not appropriate for Matlab Answer. I would even suggest it is more relevant here if it doesn't work on Octave. In case you think of removing your question and/or change your username to avoid detection of cheating on your homework: don't bother.
