Practice Rudin-style real analysis with Gradus.

The first full Gradus course package covers core material from Walter Rudin's Principles of Mathematical Analysis through structured lessons, concept dependencies, and proof-focused practice.

Course topics

• The real and complex number systems
• Basic topology of metric spaces
• Numerical sequences and series
• Continuity, differentiation, and special functions
• Riemann-Stieltjes integration and several-variable analysis

How Gradus uses the course

Each lesson is represented as a set of concepts with item families and deterministic answer specifications. The app can present lesson practice, concept-level sessions, chapter review, and cumulative review.
