Lecture 39 | Discontinuities of monotonic functions on R & its left and right limits | Tamil

Definition of monotonically increasing and decreasing functions on R with examples. Existence of left and right limits of monotonic functions at every point. Monotonic functions have no discontinuities of the second kind. Let f be a monotonic function. Then the set of points at which f is discontinuous is at most countable. ================================================ Reference book: Walter Rudin, Principles of Mathematical Analysis (Third edition).
