Week 7 of my Sunday Maths Animations is another one that started out as a cardioid. Varying a different parameter gives a completely different effect.

Cardioid Rainbow: Sunday Maths Animations Week 6
Week 6 of my Sunday Maths Animations started out as a cardioid, but quickly became something else.

Rhodonea Spheres: Sunday Maths Animations Week 4
Week 4 of my Sunday Maths Animations is my old favourite the Rhodonea curve, rendered with spheres. The ending is extremely satisfying!

Spiky Feathers and Geometric Fish
The astroid curve is an example of a hypocycloid – a curve generated by rotating a fixed point on a small circle around a larger circle. Specifically, it is a hypocycloid with four cusps.

Parametric T-shirts
I’m excited to share my new TeeMill site, selling T-shirts based on graphs of parametric equations.
There are three designs currently available, and all can be bought in loose fit or fitted, and with or without the equations that created the design displayed underneath.
You can also find GeoGebra files, where you can play with the graphs of the equations yourself, here.
Spin, Laugh and Dance
I’d like to introduce you to the graph of $x=\sin(f_1t)e^{d_1t}$, $y=\sin(f_2t)e^{d_2t}$, a curve that spins, laughs and dances.
