此计算器通过 tinh-sinh 四边形方案计算确定积分。在"集成大"文本框中键入公式。更改集成的下限和上限的默认值。单击"计算"按钮。监视算法是否收敛。当前不确定性值应稳步下降。如果算法有差异，请单击"停止"按钮。在"历史记录"选项卡中观察计算结果。 在每个级别，计算点的数量加倍，准确的数字数也加倍。您可以通过减少当前不确定性的指数来观察它。计算点的数量取决于锡辛四边形算法的积分级别和长度。 如果在精度低于计算器默认值的集成大函数中使用，则调整"所需不确定性"值。 算法的收敛并不保证所有函数和所有集成间隔。 Tanf-sinh四边形方案速度快，为多种函数提供了正确的答案。但对于某些函数和间隔，算法会有所不同。对于少数函数，该方案给出了错误的答案。

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.
