# How to get Lissajous curve like the following gif [duplicate]

parameter equation $$x= \sin(m t)$$, $$y= \sin (nt)$$,(fix $$m=13$$, $$n=18$$ not to change)

I need the picture show the generation of the curve.(start from one point to the final curve like you draw it manually )

In fact,I just want to know how to generate a curve continuously like the gif show
