How to draw the US Flag mathematically?

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 benice;

Very nice!

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi MathsIsFun,

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
of parallel lines

Hi Sumasoltin;

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