Course Description

Description

Introduction to Real Analysis provides advanced students with the theoretical foundations underlying the topics taught in a typical single variable Calculus course. Introduction to Real Analysis will cover algebraic and order properties of the real numbers, the least upper bound axiom, limits, continuity, differentiation, the Riemann integral, sequences, and series. Definitions and proofs will be stressed throughout the course. Online course materials supplement the required textbook.

Each student is assigned to a CTY instructor to help them during their course. Students can contact their instructor via email with any questions or concerns at any time. Live one-on-one online review sessions can be scheduled as well to prepare for the graded assessments, which include homework, chapter exams, and a cumulative midterm and final. Instructors use virtual classroom software allowing video, voice, text, screen sharing and whiteboard interaction.

Topics include:

  • The Real Numbers
  • Sequences
  • Functions and Continuity
  • The Derivative
  • The Integral
  • Infinite Series
  • Sequences and Series of Functions
  • Introduction to Differential Equations

See the List of Topics tab for the complete listing of topics covered.
