Step 1
Set
g ( h ) = h / 2 h / 2 f ( x ) d x h f ( 0 )
and compute
g ( 0 ) = 0 g ( h ) = 1 2 ( f ( h / 2 ) + f ( h / 2 ) ) f ( 0 ) g ( 0 ) = 0
etc. to find the Taylor expansion of g.

Step 1
Put f ( x ) = f ( 0 ) + x f ( 0 ) + x 2 f ( 0 ) / 2 + . . . so h / 2 h / 2 f ( x ) d x = h f ( 0 ) + h 3 f ( 0 ) / ( 2 3 8 ) + . . . .
