It can perform several types of integral approximations including: left endpoint, right endpoint, midpoint, trapezoidal, and simpson's rule. In addition to all of these great features, the program can calculate the error bounds for each of these tests on a given number of subintervals. Looking for a desired accuracy for your approxmation? No problem, the program can calculate the required number of subinvervals for a desired accuracy. This is the *BEST* integral approximation program available. Version 2.6 incorporates new features that make the program easier to use.
