SUMMARY
The discussion focuses on proving the orthogonal projection of triangle V, specifically the equation \( v_{1}=V \cos(\psi)+v'_{1} \cos(\theta - \psi) \). It establishes that \( v_{1} \) represents the sum of the orthogonal projections of both \( V \) and \( v'_{1} \) onto \( v_{1} \). Participants emphasize the need for clarity in the projection calculations to validate this expression. The conversation highlights the importance of understanding trigonometric functions in the context of vector projections.
