Trigonometric Functions and Their Graphs is an important topic in FSC Mathematics that focuses on the behavior and visualization of trigonometric functions. This chapter covers the six trigonometric functions, their domains and ranges, amplitude, period, phase shift, and graphical representations. Understanding these graphs helps students analyze functions, solve equations, and apply trigonometry in real-world problems. This chapter is frequently tested in FSC board exams and competitive entry tests such as NTS, ECAT, NUST, and FAST. At PLS Academy, Trigonometric Functions and Their Graphs is taught in a simple, exam-oriented manner, with special emphasis on key formulas, repeated MCQs, past paper trends, and clear step-by-step techniques to help students achieve high scores with confidence.
