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

## 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
