Conquer Calculus

Go from "I don't get it" to "I can do this" in AP Calculus. Conquer Calculus breaks calculus into 12 parts and 207 concept cards, from "what is a function" all the way to differential equations and series. Every card gives you a clear definition, the key properties, a tidy summary of the formulas, and worked examples that go from easy to hard — so you can start solving problems right after reading. What's inside • Functions, domain and range, composition, inverses • Limits and continuity, infinite limits, asymptotes, squeeze theorem • Derivatives: definition, difference quotient, product/quotient/chain rules, implicit and parametric differentiation • Applications: extrema, curve sketching, related rates, linear approximation • Antiderivatives: u-substitution, partial fractions, integration by parts, tabular method • Definite integrals: Riemann sums, the Fundamental Theorem, average value • Applications: area, volume, arc length, improper integrals • Motion, velocity and position • Differential equations: slope fields, Euler's method, separation of variables, exponential and logistic growth • Sequences and series: convergence, tests, Taylor series Why you'll keep opening it • Full solutions for every problem — not just the answer, but the idea and the steps • Graphs are drawn inside the app: crisp when you zoom in, and easy on the eyes in dark mode • Formula reference: every formula in one place, searchable in both directions • Progress is tracked automatically, so revision starts where you're weakest • Bilingual: every concept and every problem in English and Chinese • Works offline — study without a connection, and pick up updates the next time you're online Who it's for • Students taking AP Calculus AB or BC • Students previewing or reviewing university calculus • Self-learners who want the fundamentals solid Privacy No accounts, no tracking, no ads. We only record whether the App is being used, where from, and when it was last used: a randomly generated install identifier, your IP address, the country derived from it, and the last-used time (kept for 90 days). Your study progress stays on your device.
