Adding an INFO button to your directory
An information button can be useful for your directory to help you remember
the operation of the functions in the directory. In this directory, all we need to
remember is to press @TRISO to get a triangle solution started. You may want
to type in the following program:
store it in a variable called INFO. As a result, the first variable in your
directory will be the @INFO button.

Application 2 - Velocity and acceleration in polar coordinates

Two-dimensional particle motion in polar coordinates often involves
determining the radial and transverse components of the velocity and
acceleration of the particle given r, r' = dr/dt, r" = d
and, θ" = d
