Arantar: university calculus

Arantar helps you pass university calculus by practicing the way you really learn: you try, you miss, you see why, and you try again. • Calculus I, II and III: limits, derivatives, integrals, improper integrals, series, solids of revolution and double integrals. • Graphs where they help: the curve, the tangent line, the area under the integral or the hole of a limit, drawn with the numbers of your exercise. • Questions that change: many exercises bring new numbers each time, so you practice the method, not the answer. • Solution line: each exercise is worked out step by step with your own numbers. • Every mistake has its explanation: pick a wrong answer and Arantar tells you which step failed. • Review at the right moment: what you missed comes back before you forget it. • Extra courses to download: University Physics I, Statistics and probability, and clinical calculations for medicine. • Rate how hard each exam felt and compare it with how much you got right. • Works offline: the content comes in the app and your progress stays on your phone. Language: the app's screens are available in English (Profile → Language). The exercises and explanations are written in Spanish. No ads. No artificial intelligence making up answers: every question is written and checked with a computer algebra system. Arantar is made by Zymbiotek. It is not affiliated with any university.
