<p>Here is a program that will use the trapezoidal rule to approximate a definite integral:
PROGRAM: TRAP:ClrHome:Input "F(X) IN QUOTES:", Y0:Input "START(A):", A:Input "END(B):", B:Input "NO. OF DIV. (N):", N:(B - A) / N → D:0 → S:For (X, A, B, D):S + Y0→ S:End:A → X : Y0→ F:B → X : Y0→ L:D *(-F + S - L) → A:ClrHome:Disp "EST AREA=":Disp A</p>
<p>im not sure but i must be doing something wrong after i enter f(x) i get a data type error</p>
