得到了欧氏空间中，单位球面上坐标函数关于某一特定标架场的协变微分的两个等式。

We obtain two formulas about the covariant derivative of the coordinate functions on the unit sphere in Eucdidean space.

如果浏览器提供坐标有问题的话，可以将这两个函数调用分开以便于调试。

I broke these two function calls apart to help with debugging if you have an issue getting your browser to give you coordinates.

该函数将从坐标中提取longitude和latitude字段，并通过调用Document Object Model (DOM)将它们附加到列表中。

The function just extracts the longitude and latitude fields from the coordinate and appends them to a list via Document Object Model (DOM) calls.
