1. The problem statement, all variables and given/known data Write a user-defined function that determines cos(x) using Taylor Series expansion Stop adding terms when estimated error, E<=.000001 2. Relevant equations sum Sn = Sn-1 + an E = | (Sn - Sn-1)/Sn-1 | 3. The attempt at a solution function y = cosTaylor(x) Sn=1; Snm1=0; n=2; xr=x*pi/180; E=1; while E >= .000001 an=(-1)^n*xr^(2*n)/(factorial(2*n)); Snm1=Sn; Sn=Snm1+an; n=n+1; E=abs((Sn-Snm1)/Snm1); end This gives values too large compared to what they should be. I really don't understand why this doesn't work. Any help is appreciated. Thanks in advance!
