To describe a vector mathematically, we need a coordinate system (x,y,z or east,north and up). A vector has three components: k A j A i A A z y x + + = The magnitude of the vector is A=(A x 2 + A y 2 + A z 2 ) In two dimensions, ( ) j i A j A i A A y x sin cos + = + = 8 We can multiply vectors to get a scalar or another vector with magnitude...
