# parametric with EQ

- Author:

This is simple parametric motion with two stages. the functions for dx(t) and dy(t) control point D while ex(t) and ey(t) locate point E from point D. The combination of these two functions produces the required final result.
Note that the pink and green functions are separate 'parts' of the curve. This happens because we took a square root in our solution process which led to two separate answers.
