List Of Tr Nometric Iden Ies Wikipedia
These iden.ies are useful whenever expressions involving tr.nometric functions need to be simplified. An important application is the integration of nontr.nometric functions: a common technique involves first using the subs.ution rule with a tr.nometric function, and then simplifying the resulting integral with a tr.nometric iden.y..
