UP Board Class 11 Maths Book – Trigonometric Functions
The chapter “Trigonometric Functions” in the UP Board Class 11 Maths Book introduces students to the advanced concepts of trigonometry used in higher mathematics. It begins with the measurement of angles in degrees and radians, helping students understand the conversion between both systems. The chapter further explores signs of trigonometric functions in different quadrants, along with their domains and ranges.
Students learn the values of trigonometric functions at standard angles, the concept of periodicity, and the fundamental identities that form the base of all trigonometric calculations. The chapter also explains trigonometric functions of compound angles and their applications in solving real-life problems.
With clear definitions, examples, and exercise questions, Trigonometric Functions helps Class 11 students develop strong analytical and calculation skills. Mastering this chapter is essential for preparing for Class 12 trigonometry, calculus, and competitive exams like JEE and NDA.
