Multivariable Calculus Unit 3 Lecture 10: General definition of differentiability

We look at what it means to say a function like z=f(x,y) (or w=f(x,y,z)) is differentiable at a point in its domain. Two useful theorems about differentiability. #calculus #multivariablecalculus #mathematics #iitjammathematics #calculus3
