WebSep 17, 2013 · Short answer: Negative values, and any non-zero values in general, are treated as true when used as conditions. For C, there are a number of contexts in which an expression is treated as a condition. Conditions are not necessarily of type bool or _Bool; that type was only added to the language by the 1999 standard. WebThese are the magnitudes of \vec {a} a and \vec {b} b, so the dot product takes into account how long vectors are. The final factor is \cos (\theta) cos(θ), where \theta θ is the angle between \vec {a} a and \vec {b} b. This tells us the dot product has to do with direction.

WebSep 19, 2024 · When It is multiplied with a vector it changes the vector's magnitude because it only has magnitude but no direction. So then why a negative scalar rotates a vector's direction by 180 degree? For example, if the scalar is -5 then it will scale the magnitude 5 times and also rotate the vector by 180 degree. Thus it changes the vector's direction.
