Can anyone explain vectors to me please?
what you are used to thinking of as a number is called a scalar a vector is a different kind of mathematical construct often represented by an arrow in space what makes it essentially different than a scalar number is that is has both a length (magnitude) and a direction
\[1,1.358\times10^7,\sqrt3,\pi\]these are all scalars, but vector are more like so|dw:1338180068220:dw|
the length of the vector is some number, and its direction can be defined by some angle theta
