Question

find principal values of the cot-¹(✓3)​

Answer 1

Let cot-1√3 = ∅ then cot ∅ = √3 = cot ( π /6 ). We know that the range of the principal value branch of cot−¹ is (0, π) and cot ( π /6 ) = √3. Therefore, the principal value of cot-1√3 is π /6.

Answer 2

Answer:

Let cot-1√3 = ∅ then cot ∅ = √3 = cot ( π /6 ). We know that the range of the principal value branch of cot−¹ is (0, π) and cot ( π /6 ) = √3. Therefore, the principal value of cot-1√3 is π /6 .
