To write Taylor series expansion for cos(x) in MATLAB, we need to first define the x values and the number of terms in the expansion. The general formula for the Taylor series expansion of cos(x) is:
cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...
Here is the MATLAB code for calculating the Taylor series expansion of cos(x):
main.m237 chars10 lines
In this code, we first define the value of x as 0.5 and the number of terms in the expansion as 10. We then initialize the result to zero and use a for loop to calculate each term in the expansion, summing them up in the result variable. We use the built-in MATLAB function factorial
to calculate the factorials in each term.
When we run this code, it will output the value of the Taylor series expansion of cos(0.5) up to the 10th term. The more terms we include, the more accurate the result will be.
