The elementary power rule generalizes considerably. The most general power rule is the functional power rule: for any functions f and g, = = + ,wherever both sides are well defined. Special cases: If f x = x a, f x = ax a 1 when a is any non-zero real number and x is positive.; The reciprocal rule may be derived as the special case where g x = 1..You have seen quite a few tr.nometric iden.ies in the past few pages. It is convenient to have a summary of them for reference. These iden.ies mostly refer to one angle denoted , but there are some that involve two angles, and for those, the two angles are denoted and .: The more important iden.ies..In mathematics, tr.nometric iden.ies are equalities that involve tr.nometric functions and are true for every value of the occurring variables where both sides of the equality are defined. Geometri.y, these are iden.ies involving certain functions of one or more angles.They are distinct from triangle iden.ies, which are iden.ies potentially involving angles but also involving .Amazon Cognito Iden.ies.

These iden.ies are useful whenever expressions involving tr.nometric functions need to be simplified. An important application is the integration of non-tr.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..
