Wish this guy taught me Math 293 and 294 at Cornell. My guy could barely speak English, let alone explain what we were trying to accomplish. I understood that if we wanted eigenvectors perpendicular to x we'd get lift relative to flow...but this guy would have made the math a bit simpler.####[['NULL', 'Instructor', 'POS'], ['Math 293 and 294', 'Course_General_Feedback', 'NEU'], ['eigenvectors', 'Mathematical_Related_Concept', 'NEU'], ['x', 'Mathematical_Related_Concept', 'NEU']]
