Use this application to integrate a function f (z) using left endpoint approximation, right endpoint approximation, the Trapezoid Rule, Midpoint Rule, and Simpson's Rule.
Be sure to use the correct format for entering in math functions.


f (z) =
Lower bound for integral (a): Upper bound for integral (b):
Number of integration steps (n):

Result using left endpoint approximation (Ln):
Result using right endpoint approximation (Rn):
Result using Trapezoid Rule (Tn):
Result using Midpoint Rule (Mn):
Result using Simpson's Rule (Sn):

A few examples:
f (z) =
f (z) =
f (z) =
f (z) =


Correct Function Definitions: Note: These functions are case sensitive so enter them exactly as you see them.
Note: Arguments for trigonometric functions must be in radians.
