Beautiful Functions vs Calculus

Functions make sense when you can see them. Beautiful Functions turns every change in an equation into an immediate change on the graph. Move a slider, watch the curve respond, and understand what each parameter actually does - before memorizing a rule or solving an exercise. NOT JUST A GRAPHING CALCULATOR This is a visual learning environment designed to show how functions work. Watch a line cross a parabola twice, become tangent, then miss it completely. See a function reflect into its inverse. Switch the same parabola between Standard, Vertex, and Factored forms. Change amplitude, frequency, and phase, and watch every wave transform. EXPLORE WITH PURPOSE Use roots, intercepts, vertices, symmetry, extrema, inflection points, and asymptotes as visual guides instead of isolated definitions. Collapse the graph when you want to focus on an explanation, then bring it back to test your intuition. START FREE Start with Linear, Quadratic, Cubic, and Logarithmic Functions. Pro unlocks: • Linear + Quadratic • Exponential Functions • Trigonometric Functions • Function Transformations • Rational Functions • Absolute Value Functions • Inverse functions and slope relationships • Vertex and Factored form editing One-time purchase unlocks every Pro screen and feature. No subscription. Built for high school and university students, teachers, tutors, parents, and anyone who wants to understand functions instead of memorizing them. Download Beautiful Functions and see what equations mean.

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. TRY IT FIRST Chapter 1 is completely free — animations, examples and practice all work, no time limit and no account.
