Mathematics - Trigonometric Equations

Practise 22 BITSAT previous year questions on Trigonometric Equations, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Trigonometric Equations has been asked in 14 of the 16 years of BITSAT papers analysed (2009–2024), with 22 questions in all. 36% of them were easy, 45% moderate and 18% tough. Most of its questions came from 2016, with 3 questions that year. In the last three years (2022–2024) it had 5 questions across 5 papers, about 1 per paper.

The chapter's 3 topics are not weighted equally: Solving Trigonometric Equation (15 questions, 68%), Basic (6 questions, 27%), and Solving Trigonometric Inequalities (1 question, 5%) have been asked the most. Over the last five years the most frequent topics have been Basic (5), Solving Trigonometric Equation (2), and Solving Trigonometric Inequalities (1). Solving Trigonometric Equation has produced the most tough questions (3).
