Question

Principal value branch of cosec inverse x?​

Answer 1

We know that the range of the principal value branch of cosec-1(x) is [-π/2, π/2] – {0} and cosec(π/4) = √2. So, the principal value of cosec-1(√2) = π/4. We know that the range of the principal value branch of cosec-1(x) is [-π/2, π/2] – {0} and cosec(π/2) = 1.
