a. Explanation Given: The function f ( x ) = cos x and x = − 0.2 , − 0.1 , 0.0 , 0.1 , and 0.2 . The Taylor polynomials, p 2 ( x ) = 1 − x 2 2 and p 4 ( x ) = 1 − x 2 2 + x 4 24 . Calculation: Use the online calculator and obtain the absolute error. The value of | cos x − p 2 ( x ) | is shown in below Table. x p 2 ( x ) = 1 − x 2 2 f ( x ) = cos x | cos x − p 2 ( x ) | −0.2 1 − ( − 0.2 ) 2 2 = 0.98 cos ( − 0.2 ) = 0 .980066578 6 .66 × 10 − 5 −0.1 1 − ( − 0.1 ) 2 2 = 0.995 cos ( − 0.1 ) = 0 .995004165 4 .17 × 10 − 6 0.0 1 − ( 0 ) 2 2 = 1 1 0 0.1 1 − ( 0.1 ) 2 2 = 0.995 cos ( 0.1 ) = 0 .995004165 4 .17 × 10 − 6 0.2 1 − ( 0.2 ) 2 2 = 0.98 cos ( 0.2 ) = 0 .980066577 6 .66 × 10 − 5 The value of | cos x − p 4 ( x ) | is shown in below Table b.
