NCERT Class 12 Maths · Chapter 2 Inverse Trigonometric Functions · Exercise 2.1 Question 8
Find the principal value of cot⁻¹(√3).
💡 Concept Hints
- Recall the principal range of the inverse function before simplifying.
- Find an angle with the required trigonometric value, then verify it belongs to the principal range.
✅ Step-by-Step Solution
Final Answer: π/6
- The principal range is (0,π).
- cot(π/6)=√3.
- The angle π/6 belongs to that range, so it is the required value.
