In this Fast Track Math lesson, we break down when and why a function is not differentiable using clear graphs and intuitive explanations.
You’ll learn the three main reasons derivatives fail to exist:
Corner points (like absolute value functions)
Vertical tangents (infinite slope)
Discontinuities (holes and jumps)
This lesson is essential for Calculus 1, AP Calculus AB, and anyone trying to truly understand what derivatives mean beyond formulas.
📌 In this video, you’ll learn:
How to recognize nondifferentiable points from a graph
Why continuity does not always guarantee differentiability
How left-hand and right-hand slopes explain corners
How vertical tangents create infinite derivatives
⏱️ Fast explanations. Visual intuition. No fluff.
