A friendly introduction to real analysis.
We are developing an online beginner's course (based on MATH 131A/131B at UCLA^{1}).
Join Howard for Office Hours each week. We use this time for tutoring real analysis students.
We post animated videos introducing concepts in real analysis and math research.
Join our Patreon to receive content updates and provide input for future work.
We love hearing from you; please reach out!
The diameter of a set is the least upper bound on the distance between pairs of points in the set. This graphic shows why the diameter of two overlapping sets is bounded above by the sum of the diameters of the individual sets.#realanalysis #iteachmath #matheducation pic.twitter.com/OHuRLcqbyr

To show a set is open, we often proceed by picking an arbitrary element in the set and showing a ball around that point is also in the set. This graphic illustrates the intuition for proving the set {x : x_1 > x_2} in the plane is open. #realanalysis #iteachmath #matheducation pic.twitter.com/VxVmySS47X

A limit point of a set can be defined by saying each ball about the point contains a distinct point that is in the set. How does this relate to "limit" in the name? Here's one way to see the connection.#realanalysis #iteachmath #matheducation pic.twitter.com/hT8L66D4Dn

We are happy to share a minilesson on sequence convergence, which shows how to write a direct proof from the definition of convergence. #realanalysis #uclamathhttps://t.co/OtjOE5Dt0B
