See Math

An invertible function

Not continuous and not differentiable

A function that's not one-to-one

Continuous, but not differentiable

Continuous and differentiable


  1. Hi Hyunhwa,

    You've taken some interesting photos to represent the different concepts. It would help the reader understand your post better if you included captions or comments that describe what each photo is trying to show.

    Nice work!


  2. Nice pictures. I especially like the picture of the sail boat representing a function that is continuous but not differentiable because of the cusp that the sail makes. Good work
