I have programmed into Mathematica a way for it to evaluate a definite integral using Simpson's Rule. This works fine for any integral which adheres to the Fundamental theorem of calculus. When given an integral which does not work with the fundamental theorem of calculus, how do I get Mathematica to compute this integral using my formula for simpson's rule? This is my formula: simp[f_,{x_,a_,b_,n_Integer}] := Module[{s=0,ne,k, j}, ne = n + If[IntegerQ[n/2],0,1];k:=2 (b-a)/ne; Do[s=s+N[(f/.x->(a + j k))] + N[(f/.x->(a + (j-1) k))] + N[4 (f/.x->(a + (j-(1/2)) k))],{j,1,ne/2}]; N[(k/6)]*s] Thank you, Dean -- **************************** * M.
