Best ResponseYou've already chosen the best response.0What is the difference between component and projection?? Consider 2 vectors, \[\vec a\] and\[\vec b\] The cosine of the angle between them is given by, \[\cos(\theta)=\frac{\vec a.\vec b}{\vec a\vec b}\] Then the component of a along b is the magnitude of a times the cosine of the angle between \[\vec a\cos(\theta)=\vec a . \frac{\vec a. \vec b}{\vec a\vec b}=\vec a \frac{\vec b}{\vec b}=\vec a.b\] where b is the unit vector along b, this is the same as projection of a on b ??

Best ResponseYou've already chosen the best response.0projection of \(a\) onto \(b\) is defined as the component of \(a\) along \(b\) : \[\large \text{proj}_b~a ~~=~~ \text{comp}_b a ~~=~~ \frac{a\cdot b}{b\cdot b} b\]
