The smallest periodic cycle is 2π but for tangent and the cotangent it is π.
The trig functions are the periodic functions. The cos and sec functions are even functions the rest other functions are odd functions. Let us discuss the formulas given in the table below for functions of trigonometric ratios(sine, cosine, tangent, cotangent, secant and cosecant) for a right-angled triangle.īelow are the identities related to trig functions. For each of these functions, there is an inverse trigonometric function. The trigonometric functions include the following functions: sine, cosine, tangent, cotangent, secant, and cosecant. These functions often appear in the solution of differential equations and functional equations. For example, any periodic processes can be represented as a sum of trigonometric functions (Fourier series). Applications of trigonometric functions are extremely diverse. Trigonometric functions describe the relation between the sides and angles of a right triangle. Trigonometric functions are elementary functions, the argument of which is an angle. Therefore, solving these NCERT questions helps students build a solid foundation in trigonometric functions. Exams like JEE Mains and NEET ask questions from NCERT textbooks. NCERT questions are important for both entrance and competitive exams. The notes also helps students quickly review a chapter before exams.
Students can fully trust these NCERT book answers for class exercises and assignments. Vidyakul's top math teachers have created notes for Chapter 3 - Trigonometry Practice.
