Course Highlights

  • Lessons for each major topic
  • Graphics for example proofs
  • Ability to ask questions

Analysis Taught via Graphics

Abstract definitions and theorems can be hard to digest. Our course makes concepts concrete by visualizing definitions and proof arguments.
Graphics Examples

Focus on Proof Techniques

Analysis courses usually focus on key theorems and too often leave details "as an exercise for the reader." However, students often experience the most headache in how to write proofs for homework and exams. Thus, we focus on supplying students with high-level outlines and walk-through proof examples.

FAQ

  • Will this help me with my class at university?

    Yes! This is precisely our goal, to help students better understand the concepts and how to apply them. We expect many students to be simultaneously enrolled in university courses (e.g. MATH 131A at UCLA).

  • What does it mean to be a beta student?

    Course memberships are $39/month for the course content; the ability to join Zoom office hours usually costs $30/month. However, current beta users have early access to Typal Academy while content is still undergoing much growth. To remedy any gaps in lesson plans, all beta students are welcome to join office hours with their membership.

  • What is so different about adding graphics?

    Real analysis concepts are typically geometric in nature, and seeing canonical examples can go a long ways in developing intuition. Real analysis textbooks often either do not contain diagrams or very few (that are of low quality).

  • Do I need to be enrolled in a university?

    Not at all! We aim to empower aspiring scholars to learn effectively without forking out money to expensive universities. Some members even find this resource useful for preparing to go back to school for a graduate degree.

  • What are the lessons like?

    Each lesson includes key definitions and theorems along with several walkthrough examples that include both proofs and illustrative diagrams. These no-fluff lessons are written with a lighter tone than most textbooks, with sidebars from instructors giving intuition for the examples. Some lessons also include video mini-lectures.

  • How long will this course take?

    The content for this course is typically studied over the course of 10 weeks. Yet, you can adjust that timeline as needed to suit your needs.

  • What's the cost?

    Access to the course contents costs $39 per month. All current users (i.e. beta users) can also attend weekly office hours with Eric on Sunday evenings.

  • What do I do if I have a question?

    Each lesson and quiz has an associated discussion tab where you are welcome to ask clarifying questions to the community. We update lessons to better clarify material based on community comments. You are also welcome to ask for more examples on a particular topic!

  • Do I need a textbook?

    Nope! The content in our online course is self-contained. If you also want to complement your analysis studies with a textbook, we certainly encourage this!
