A trigonometric table is a table that summarizes the trigonometric ratios for various angles of a triangle. By looking at this table, we can easily get the trigonometric ratio we need for our calculation result/further data processing. There are usually two types of trigonometric tables, the special degrees table and the all degrees table.

Here is the list of formulas for Class 11 students as per the NCERT curriculum. All the formulas.

Trigonometry formulas for Class 10 are provided here for students. Trigonometry is the study of relationships between angles, lengths, and heights of triangles. It includes ratios, functions, identities, and formulas to solve problems based on it, especially for right-angled triangles.

An identity, is an equation that is true for all allowable values of the variable. For example, from previous algebra courses, we have seen that. (4.1.1) x 2 − 1 = ( x + 1) ( x − 1) for all real numbers x. This is an algebraic identity since it is true for all real number values of x. An example of a trigonometric identity is cos 2 + sin 2.
