 ## De Casteljau's algorithm
 
 There's a mathematical formula for Bezier curves, but let's cover it a bit later, because
-[De Casteljau's algorithm](https://en.wikipedia.org/wiki/De_Casteljau%27s_algorithm) it is identical to the mathematical definition and visually shows how it is constructed.

 First let's see the 3-points example.
