Is this a typo? (Complex positions of input and output links)

Click For Summary
SUMMARY

The discussion centers on a potential typo in a mathematical expression involving complex vector forms. Participants agree that the absence of a "j" in the sine function indicates a typographical error. The consensus confirms that the correct representation should include this imaginary unit to accurately reflect the complex nature of the equation. This clarification is crucial for anyone working with complex numbers in mathematical contexts.
