MIT 18.100A Lecture 14: Limits of Functions in Terms of Sequences and Continuity
by Casey Rodriguez · MIT OpenCourseWare
MIT lecture defining continuity via epsilon-delta and sequences. It opens a five-lecture run (Lectures 13-17) on function limits, continuity of sine and cosine, Dirichlet's function, the min/max and intermediate value theorems, and uniform continuity.
