Description
This lecture discusses the conditions for a function to be non-differentiable at a point in R2, emphasizing the importance of directional derivatives and the implications of the differentiability theorem. Through examples, the instructor illustrates scenarios where a function can be derivable but not of class C1 or C2, highlighting the complexity of tangents and surfaces in multivariable calculus.
