Suppose the tradpezoidal rule from a to b = ((b-a)/2)(f(a)+f(b))-(((b-a)^3)/12) f"( ) for f , [a,b]. Derive the error estimate for the composite trapezoidal rule with equal spaced: from a to b f(x)dx= (h/2)[f(a)+f(b)+2 for i=1 to N-1 f( )-((b-a)/12) f"( ) where h= (b-a)/N, =a+ih, [a,b]. I hope some one can help more or at least lead me in some sort of direction because I thought that the error for comp. trap. rule was ((b-a)/12) f"( ) so I'm not sure at all of what to do in this problem. Thank you
