If your math teacher told you that mathematics is everywhere, believe him. Almost all the things that we see around (even things that we do not see) are related to mathematics — even potato chips. Yes, even potato chips.

Some potato chips, particularly Pringles (I hope they give me 500 bucks for this), are in a shape of a saddle. In mathematics a saddle-shaped graph is called a hyperbolic paraboloid (see left figure).

A hyperbolic paraboloid quadratic and doubly ruled surface given by the Cartesian equation . Now, whatever that means will be discussed when you take your analytic geometry course.

For now, let’s be happy that we know that even potato chips can be modeled by graphs. 🙂
