Question

Considering only the principal values of inverse trigonometric functions, the number of positive real values of $x$ satisfying a given equation is:

Accepted Answer

*(The exact equation for this question was not present in extractable form in the source PDF --- only the options and answer key survived. The number of positive real solutions is confirmed by the source to be 1, but the worked derivation could not be reliably reconstructed.)*
