Mathematics - Inverse Trigonometric Functions

Practise 18 BITSAT previous year questions on Inverse Trigonometric Functions, compiled from papers spanning 2011 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.

Inverse Trigonometric Functions has been asked in 13 of the 16 years of BITSAT papers analysed (2009–2024), with 18 questions in all. 28% of them were easy, 44% moderate and 28% tough. Most of its questions came from 2024, with 2 questions that year. In the last three years (2022–2024) it had 5 questions across 5 papers, about 1 per paper.

The chapter's 6 topics are not weighted equally: Converting one Inverse T function to other Inverse T (6 questions, 33%), Sum and difference of angles (4 questions, 22%), and Infinite Series (2 questions, 11%) have been asked the most. Converting one Inverse T function to other Inverse T has also led over the last five years, with 3 questions. Converting one Inverse T function to other Inverse T has produced the most tough questions (2).
