what did i do wrong here

if true
 clear, clc
x1=unput('Enter the angel in dgree');
x=x1*pi/180;
tol=10^(-7);
f=(0);
for n=0:100
  f=f+(-1)^(n)*x^(2*n)/factorial(2*n);
  s(n+1)=f;
  if(n>1)
      err=abs((s(n+1)-s(n))/s(n));
      if err<tol
          break;
      end
  end
end
f1=cos(x);
fprintf('cos(%d)=%f\n',x1s(end));
fprintf('Actual Value of cos(%d)=%1.8f\n'x1,f1);
end

x1=input('Enter the angel in dgree');
x=x1*pi/180;
tol=10^(-7);
f=(0);
for n=0:100
  f=f+(-1)^(n)*x^(2*n)/factorial(2*n);
  s(n+1)=f;
  if(n>1)
      err=abs((s(n+1)-s(n))/s(n));
      if err<tol
          break;
      end
  end
