Upon completion of this chapter we will be able to describe such things as the motion of a top, or of a bicycle. To get a unit vector from any old vector, you "normalize" that vector, which gives you a new vector with the same direction but a magnitude of 1. Here, we will first state the general definition of a unit vector, and then extend this definition into 2D polar coordinates and 3D spherical coordinates. Find the unit vector with the direction of vector . Express it in both bracket format and unit vector component format. Any vector whose length 1 is called a unit vector; unit vectors will usually be denoted by e. Firstly, directions will most likely be specified as angles in standard position (positive angles rotate counterclockwise, starting from the positive x-axis An alternate notation is the use of two unit vectors i 1,0 and j 0,1 so that v 6 i 3 j The "hat" notation, not used in our text, is to indicate a unit vector, a vector whose magnitude (length) is 1. For example, x, y and z are the parameters that define a vector r in Cartesian coordinates: r =ˆıx+ ˆy + ˆkz (1) Similarly a vector in cylindrical polar coordinates is described in terms of the parameters r, θ How to Find the Angle Between Two Vectors. If is a vector of components (3, 4), find a unit vector in the same direction. This gives each vector a magnitude and direction. y-direction.

Without a vector cross product calculator, it is hard to know how to calculate the cross product
