Find the principal value of `cosec^(-1)(2/sqrt3)`.

Explanation

To find the principal value of \( \csc^{-1}\left(\frac{2}{\sqrt{3}}\right) \), we will follow these steps:

### Step 1: Define the variable
Let \( y = \csc^{-1}\left(\frac{2}{\sqrt{3}}\right) \). By the definition of the cosecant inverse function, we have:
\[ \csc(y) = \frac{2}{\sqrt{3}} \]
