Triple Integral Calculator Level 2

This calculator computes definite triple integrals of real functions with three real variables,utilizing triple tinh-sinh quadrature scheme. Although some precaution about theoretical foundation of tanh-sinh quadrature exists, in practice the scheme is almost universal. Numerical values are calculated with Precision 15-16 Digits. All calculation results are reflected in History rich-text-Box, which can be saved in file or printed.
