Class 12 Maths · Inverse Trigonometric Functions · Assertion Reason #26

Assertion: The principal value of tan⁻¹(−√3) is −π/3. Reason: The principal arctangent is the inverse of tan restricted to (−π/2,π/2).

✅ Step-by-Step Solution

Final Answer: Option (A): Both A and R are true, and R correctly explains A.
  1. tan(−π/3)=−√3 and −π/3 lies in the specified principal interval, selecting that inverse value.
