1. The problem statement, all variables and given/known data Use Taylor's theorem to obtain an upper bound of the error of the approximation. Then calculate the exact value of the error. cos(.3) is approximately equal to 1 - (.3)^2/2! + (.3)^4/4! 2. Relevant equations 3. The attempt at a solution I came up with upper bound saying Rn = (-sinz/5!)*(.3)^5 < (.3)^5/5! so the upper bound is (.3)^5/5! which is about .00002 But for the exact error I have no idea how to calculate it. There aren't any examples in my textbook.
