Скачать или смотреть When is a Function NOT Differentiable? | 4 Key Cases Explained with Examples

Did you know that not all functions have derivatives everywhere? In this video, I break down the four main cases of non-differentiability and show you exactly why a function can fail to be differentiable at certain points.

📌 What You’ll Learn:
✅ Cusp Points – Sharp turns where the derivative is undefined
✅ Endpoints – When a function stops abruptly
✅ Discontinuities – Jumps, holes, and breaks in the function
✅ Vertical Tangent Slopes – Where the derivative becomes infinite
✅ Step-by-step examples with illustrations to make each case clear
