Start your practice with these. Each one has appeared in several different years, so it is worth knowing the question styles.
What the syllabus covers
Trigonometric identities and functions, inverse trigonometric functions and their properties.
A checklist to tick off:
- Trigonometric identities and functions
- Inverse trigonometric functions and their properties
What to focus on
Identities and inverse trigonometric functions. Domain and range matter in the inverse functions.
A study plan for this chapter
Because its share has been shrinking, give it a compact, focused pass and avoid over-investing, but do not skip it. If you divide your Maths time in proportion to recent weightage, this chapter earns about 5% of it.
- Day 1–2: a fast pass over theory and the standard results.
- Day 3: chapter-wise PYQs, then log the mistakes.
- Ongoing: a quick look before each mock test.
