Publisher Description



This calculator computes definite integrals by tinh-sinh quadrature scheme. Type formula into Integrand text-box. Change default values of lower and upper limits of integration. Click Calculate button. Watch if the algorithm is converging. The Current Uncertainty value should be steadily decreasing. If the algorithm is diverging, click Stop button. Observe results of calculation in History tab. At each level the number of calculation points doubles and so does the number of accurate digits. You can watch it by decreasing exponent of current uncertainty. The number of points of calculation depends on level and length of interval of integration for tinh-sinh quadrature algorithm. If you use in integrand functions with accuracy lower than the default for the calculator, then adjust Desired Uncertainty value. The convergence of algorithm is not guaranteed for all functions and all intervals of integration. Tanf-sinh quadrature scheme is fast and and gives right answer for large variety of functions. But for some functions and intervals the algorithm diverges. And for few functions the scheme gives wrong answer.

EULA - End User License Agreement



1. You may install a copy of the Software on your personal computers. For each paid license you are given five available hardware profiles. One profile is considered as main and four as alternative. Each hardware profile is based on processor. You may install Software either on five computers at once, or install on one computer and keep four available profiles for future use, or in any other combination. Once activated a profiles becomes a used profile and number of available profiles decreases. A used profile cannot be replaced. For example, if a processor on your computer breaks down, you will have one main profile and three alternative profiles. If you have multiple operating systems on your computer, then you may install and activate the Software on each operating system under one profile. You may install and activate the Software on any virtual machine, but it can take an available profile, since virtual machines usually have different information for processor. If you have paid for a license, you may install and activate any past and future version of the Software. A paid license has no time limit. Activation of the Software requires internet connection. Once activated the Software does not require internet connection.
2. You may not reverse engineer, decompile, disassemble or otherwise attempt to discover the source code of the Software.
3. You may not alter or modify the Software or create a new installer for the Software.
