Evaluate derivative of sin(x) at x=1 using divided difference formula (sin(1+h) - sin(1))/h, for h=0.1,0.01,0.001 and 0.0001. Utilize base 10 floating-point arithmetic with 4 digits. Compare with exact answer, and describe results. Suppose that in arithmetic registers, only 1 arithmetic operation is done at the time, with result rounded using correct rounding.
