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 • 108 interactive concept animations — play, scrub and watch the key change happen instead of imagining it • 327 worked examples with complete solutions, visual hints and the mistakes students usually make • 1,215 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.
