The chapter “Trigonometric Functions” in NCERT Class 11 Maths introduces the basics of trigonometry in detail, expanding from earlier classes. It explains trigonometric ratios, identities, signs of trigonometric functions, and their values in different quadrants. Students also learn how to measure angles in degrees and radians, along with the concept of principal values and general solutions of trigonometric equations.
Important topics include graphs of trigonometric functions, domain and range, periodicity, and transformations. The chapter provides stepwise derivations, solved examples, and exercises to strengthen conceptual understanding.
By practicing regularly, students develop accuracy in solving trigonometric problems, which are essential for higher mathematics.
This chapter is crucial not only for Class 11 exams but also for competitive exams like JEE, where trigonometry forms an important part of the syllabus.
