This is not a bird (or a moustache)

Our image of the week may look like a bird in flight...

Image by Hamid Naderi Yeganeh.

...but it’s actually a collection of points in the plane given by a mathematical formula. To be precise, it’s a subset of the complex plane consisting of points of the form

  \[ \lambda A(t)+(1-\lambda )B(t), \]    


  \[ A(t)= 3(\sin (t))^{3}- \frac{3i}{4}\cos (4t) \]    


  \[ B(t)= \frac{3}{2}(\sin (t))^{5} - \frac{i}{2}\cos (3t) \]    

for $0\leq t \leq 2\pi $ and $0\leq \lambda \leq 1.$

The image was created by Hamid Naderi Yeganeh. You can see more of Hamid's images on this website and on the American Mathematical Society website.
