Calculus X: College and AP Calc Test Prep and Tools for iOS

By Express Study $4.99

Developer's Description

Calculus X is the most effective study tool for calculus at the AP or intro college level. It integrates free response questions, concise videos, quizzes, formula sheets, scratch pad and references to make the study process efficient, easy and mobile.

If youre a busy student, finding enough time to study for each calculus exam is a challenge. We have used the latest developments in educational psychology to build an app that maximizes productivity and helps you learn and do calculus as quickly as possible.


-Over 800 multiple choice questions with detailed solutions.

These conceptual based questions help you to learn calculus in a deep and intuitive way. They can all be answered without a calculator, pen or paper; making the study process as mobile as possible.

-Over 75 beautiful 720p videos which solve free response style questions in step-by-step detail.

These concise videos were designed specifically for the mobile device and solve the problems clearly and systematically in order to develop your problem solving intuition. They use narration and detailed visual guidance to increase understanding of the solution method. More video content coming soon.

-Extensive formula sheets accompany each chapter for quick access to all formulas from intro calculus, and all the necessary formulas from pre-calculus. Plus referenc e

-Fun and easy-to-use scratch pad allows you to do calculations on the fly, without the need for pencil and paper.

-Reference materials include: trigonometric identities, differentiation rules, limit laws, key theorem statements, derivatives of all common functions, and more.


- Students taking Calculus 1 or Calculus 2 in college

- Students taking AP calculus in high school

- Students studying for exams in different fields who need to review calculus

- Anybody interested in learning calculus
