In mathematics, an "identity" is an equation which is always true, regardless of the specific value of a given variable. Need a custom math course? K12 College Test Prep. Logically, mathematical identities are tautologies; that is, they are expressions which restate the same expression in a different way. In other words, the identities allow you to restate a trig expression in a different format, but one which has the exact same value. There are loads of trigonometric identities, but the following are the ones you're most likely to see and use.

In Trigonometry, different types of problems can be solved using trigonometry formulas. These problems may include trigonometric ratios sin, cos, tan, sec, cosec and cot , Pythagorean identities, product identities, etc. Learning and memorizing these mathematics formulas in trigonometry will help the students of Classes 10, 11, and 12 to score good marks in this concept. They can find the trigonometry table along with inverse trigonometry formulas to solve the problems based on them. Below is the link given to download the pdf format of Trigonometry formulas for free so that students can learn them offline too. Trigonometry is a branch of mathematics that deals with triangles. Trigonometry is also known as the study of relationships between lengths and angles of triangles.

In trigonometry , trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities , which are identities potentially involving angles but also involving side lengths or other lengths of a triangle.
