(MATLAB QUESTION). How to modify this function?

function [ approxCos ] = myTaylorApproximation( x ) %enter your code here end

**Given below is the code i have got for findFactorial, in case it needs here.

function [ nFactorial ] = findFactorial( n ) nFactorial = 1; for i = 2:n nFactorial = nFactorial*i; end end **
