Question

the principle value of tan-1 (-1) is​

Answer 1

Answer:

Solution: If the principal value of tan−1 x is θ then we know, - π2 < θ < π2. Therefore, the principal value of tan−1 (1/√3) is π6.

Answer 2

Step-by-step explanation:

Solution: If the principal value of tan−1 x is θ then we know, - π2 < θ < π2. Therefore, the principal value of tan−1 (1/√3) is π6.
