CBSE Class 12 Mathematics 2026 Main Paper 65/5/3 · Question 5 (Inverse Trigonometric Functions)

Which inverse trigonometric function has an incorrectly listed principal range?

✅ Step-by-Step Solution

Final Answer: arccsc: [−π/2,π/2]
  1. For arccsc the principal range excludes zero because cosecant is undefined there.
