We search the internet for comprehensive, in-depth material on upper-level mathematics including calculus and differential equations. Then, we integrate the best videos and links with our own discussion to help you learn, understand and use calculus. This app is not meant to replace your book or class materials but to supplement and enhance them or to refresh your skills.
You will find hundreds of practice problems, all with complete solutions, some in videos, some written out, so that you can check your work and really UNDERSTAND calculus and know how to USE it.
Precalculus, Limits, Learning Techniques, Articles and Tools are all free. You can then purchase only the sections you need including Derivatives, Integrals and coming soon, Infinite Series, Multi-Variable Calculus and Differential Equations.
