此計算機通過 tinh-sinh 四邊形方案計算確定積分。在「集成大」文字框中鍵入公式。更改整合的下限和上限的預設值。按下「計算」按鈕。監視演算法是否收斂。當前不確定性值應穩步下降。如果演算法有差異，請按兩下"停止"按鈕。在「歷史記錄」選項卡中觀察計算結果。 在每個級別，計算點的數量加倍，準確的數字數也加倍。您可以通過減少當前不確定性的指數來觀察它。計算點的數量取決於錫辛四邊形演算法的積分級別和長度。 如果在精度低於計算機預設值的集成大函數中使用，則調整"所需不確定性"值。 演算法的收斂並不保證所有函數和所有整合間隔。 Tanf-sinh四邊形方案速度快，為多種函數提供了正確的答案。但對於某些函數和間隔，演算法會有所不同。對於少數函數，該方案給出了錯誤的答案。

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.
