Calculus: Learn & Practice

Calculus you can see is calculus you can learn.

Calculus: Learn & Practice turns a full first-year calculus course into one clear path: build intuition with an interactive animation, follow a worked example step by step, then prove to yourself you've got it with instantly graded practice.

WHAT'S INSIDE
• 111 interactive concept animations — play, scrub and watch the key change happen instead of imagining it
• 336 worked examples with complete solutions, visual hints and the mistakes students usually make
• 1,246 practice problems graded the moment you submit, each with a full solution
• Math-history stories with the original problems: Zeno's paradoxes, Archimedes' π, Fermat and Descartes' fight over tangents
• Mistake tracking and mastery per concept, so you know exactly what to review
• Spaced review that brings a topic back right before you'd forget it
• Study Desk: a 2-minute micro-experiment every day, a Lab Notebook for your own conjectures, and a library of 219 counterexamples
• A searchable library of 12 chapters, filterable by topic, tag and difficulty

TOPICS COVERED
• Limits and continuity
• Derivatives and differentials
• Applications of derivatives — optimization, related rates, MVT, curve sketching, L'Hôpital's rule, Taylor polynomials
• Integrals — FTC, substitution, integration by parts, partial fractions, improper integrals
• Applications of integration — area, volume, arc length, work
• Differential equations
• Infinite series — convergence tests, power series, Taylor and Fourier series
• Multivariable differential calculus — partial derivatives, gradient, tangent planes, Lagrange multipliers
• Vectors and 3D analytic geometry
• Multiple integrals — double and triple integrals, cylindrical and spherical coordinates
• Line and surface integrals — Green's, divergence and Stokes' theorems

Great for Calculus I, II and III, AP Calculus AB/BC review, and exam prep.
