You can extract a page text using the following code: (check CommonUtil.getPageText())

String mPageText = null;        
Page mPage = mDocument.GetPage(pageIndex);
mPage.ObjsStart();
mPageText = mPage.ObjsGetString(0, mPage.ObjsGetCharCount() - 1);
mPage.Close();

~~But there is no API to detect whether the text is a mathematical equation or not.~~

PDF doesn't specify a way to encode or represent maths inside documents so there's no way to detect maths formulas and even less to copy properly formatted text in a reliable way.

I suggest you look at the video at below link:
