Hi I thought I would share with this with you
This is the sort of thing that you can draw with the help of an online graphing program called Desmos.
I love this program. I use it almost every day. I don't use it to draw cool pictures like this one. I just use if for every day maths.
Anyway, check it out.
This web page is the minion. It includes all the equations that were used to draw it.
From there you can click on the 3 horizonal stripes on the left of the screen and click new and start playing. try just drawing a graph like y=x 2+5 or something.
This is a FABULOUS program.

Try this in Desmos: (16 (sin t)^3, 13 cos t - 5 cos 2t - 2 cos 3t - cos 4t).
You'll have to extend the domain of t a bit...
Hmm, I guess I'm a couple of weeks early.

I like Serena:

Try this in Desmos: (16 sin^3 t, 13 cos t - 5 cos 2t - 2 cos 3t - cos 4t).
You'll have to extend the domain of t a bit...
Hmm, I guess I'm a couple of weeks early.

That is really cool ILS. Thanks
I drew one of these for someone a while back. Mine wasn't a parametric equation.
The equation was probably very similar BUT it LOOKED completely different.

In order to get it to work I think that you will need to type it like this.
The domain is given in the slider. and yes you will need to make the number bigger.
Take a look. It's fun!

(16 (sin t)^3, 13 cos t - 5 cos(2t) - 2 cos (3t) - cos (4t)).
