Please somebody help me rewrite and expand this Formular:
Unfortunately I cannot paste the formular here. I copied but cannot paste it here. Pls help in case of another time. However, the formular ( in words ) goes thus:
Integral(a,b) f(x) dx approx h/2 SUM[i=0,n-1][f(xi) +f(xi + 1)].
Thanks

If you are doing integration in discrete domain , you can do FOR or WHILE loop for it , as integration is a summation .

ARE you sure you need c++?? looks more matlab here then c++
