a. Explanation Given: The function f ( x ) = ( 1 + x ) − 2 . Calculation: Result used: The n th-order Tayler polynomial centered at a is as follows, p n ( x ) = f 0 ( a ) 0 ! ( x − a ) 0 + f ′ ( a ) 1 ! ( x − a ) 1 + f ″ ( a ) 2 ! ( x − a ) 2 + ⋯ + f n ( a ) n ! ( x − a ) n . Calculation: The n th-order Tayler polynomial centered at a = 0 is as follows, p n ( x ) = f ( 0 ) + f ′ ( 0 ) 1 ! ( x ) + f ″ ( 0 ) 2 ! ( x ) 2 + ⋯ + f n ( 0 ) n ! ( x ) n (1) The value of f ( x ) = cos ( x ) and its derivatives at x = 0 as shown in the below table. n f n ( x ) f n ( 0 ) 0 f ( x ) = ( 1 + x ) − 2 f ( 0 ) = 1 1 f ′ ( x ) = − 2 ( 1 + x ) − 3 f ′ ( x ) = − 2 2 f ″ ( x ) = 6 ( 1 + x ) − 4 f ″ ( 0 ) = 6 Substitute 0 for n in equation (1) and obtain p 0 ( x ) b.
