Hi Everyone!

I don't know if this is cool or not: **Drawing a US Flag using Inequalities**.

It's really a practical application of mathematics.

Hi MathsIsFun,

Thank you for your appreciation.

The following image is the original graph (of inequality) of the first picture in the post "Monster Cow".

Hi All!

A five-pointed star (☆) can be obtained by drawing five lines.

Based on this, I made an animation by drawing five collections

Hi Sumasoltin;

I would have to copy the entire page to do that. Could be copyright problems.
