To log in and use all the features of Khan Academy, please enable JavaScript in your browser. In the Cartesian coordinate system, the first two unit vectors are the unit vector of the x-axis i^i^ and the unit vector of the y-axis j^j^. In the above figure, the components can be quickly read. If Trooper runs 20 m west before taking a rest, what is his displacement vector? In polar coordinates, angles are measured in radians, or rads. Better than just an app, Better provides a suite of tools to help you manage your life and get more done. You could also view this bigger vector. The numbers AxAx and AyAy that define the vector components in Equation 2.11 are the scalar components of vector AA.
