Why index notation?
Vectors are objects that have properties that are independent of the coordinate system that
they are written in. Vector notation is advantageous since it is elegant and deals with vectors
as single objects rather

6. Velocity and Acceleration
A particle moving in space sweeps out a curve. The position vector
~r(t) = x(t) + y(t)
+ z(t)k = hx(t), y(t), z(t)i,
is naturally a function of time t. For example, the cycloid
~r(t) = ht sin t, 1 cos ti.
