Saa 32:00, the prove ni the component e na p esawa na b. Lakini nadhani the e inapaswa be perpendicular kwa the lin(1:e), si kwa take the y components... i.e. saa 32:00, kwa the uthibitisho, there ni dhana kwamba the x component ya b,e,p are the same.Hata hivyo, ni great video series kwa review. :>####[['e', 'Mathematical_Related_Concept', 'NEG'], ['video series', 'Course_General_Feedback', 'POS']]
