Question: 5 points give the taylors series for fx cos...

Question details

[5 points] Give the Taylors series for f(x) = cos x about the point 0, in a form so that the (2n)th term (for a general n) of the Taylor polynomial t2n(x) of degree 2n and the remainder R2n+2 are shown explicitly. Using R2n+2, give, in terms of n and x, an upper bound (as sharp as you can) for the (absolute value of the) error in the approximation to cos x
arising from t2n(x).
