## Acknowledgements

### This project would not have been possible without the support of some very thoughtful and generous people around us.

### The SPARK Grant Program at Brandeis University

We would like to extend a HUGE Thank You to the SPARK Grant Program
(through the Office of Technology Licensing at **Brandeis University**),
whose generosity made it possible to take this project from a proof of concept
into a fully fledged website, full of the features and connectivity we wanted
to pursue. Their contribution allowed us to access more resources (particularly
the non-technical) and expand our team. Thank you for making our work possible,
and allowing us to pursue an impactful solution to a human problem.

### Rebecca Torrey

A special thanks to Rebecca Torrey, a Mathematics professor at Brandeis University, who has aided, guided, and supported this project from the very start, and has been key in bringing this website to life. Her unparalleled experience as a Mathematics educator shaped the site in too many ways to count, and her support in pursuing the further development of the project allowed us to take our site from an independent project to a reality. Thank you for everything.

### The first set of content on CalcU was taken from various textbooks, so the existence of this entire project is thanks to the generosity of various professors and the availability of open source textbooks.

### This project wouldn't have been possible without the hard work and generosity of the following professors, teachers and open source legends:

### Calculus, Early Transcendentals

**Calculus, Early Transcendentals**
is an online, open source calculus textbook written by David Guichard.
We'd like to thank Professor Guichard, as this textbook has been a wonderful
resource that has been folded in to the heart of our database, and makes
the site so much stronger for it. Thank you for providing your work to the
open source community!

### Trigonometry by Michael Corral

**Trigonometry by Michael Corral**
is a GNU free documentation math textbook focused mainly on trigonometry,
written by Michael Corral. Thanks you Professor Corral for authoring this book and making it publicly availible,
which makes up the foundation of CalcU's trigonometry section,
and is an integral component of the open source resources available in Trigonometry.

### Gantert Geometry Textbook

**Gantert Geometry Textbook**
is a geometry textbook written by Ann Xavier Gantert, and made available under a creative commons license.
We'd like to thank Professor Gantert for this contribution, as this textbook comprises a majority of the site's geometry section,
and is a comprehensive and approachable resource for students around the world.

### Calculus Refresher

**Calculus Refresher**
is a calculus text written by Paul Garrett. This book has been helpful in expanding our
section of calculus content and learning material, and Professors Garrett's explanations comprise
many of our highlighted explanations for their clarity and simplicity.

### Precalculus, 3rd Edition

**Precalculus, 3rd Edition**
is a comprehensive precalculus textbook, written by Carl Stitz and Jeff Zeager. Thanks to Professors Stitz and Zeager, we've
been able to include an enormous precalculus and algebra section on CalcU. These two topics are traditionally
stumbling blocks for students, and we are confident that the Stitz Zeager text will help students begin thinking
of mathematics in a more thorough maner.

### First Year Calculus

**First Year Calculus**
is a calculus textbook written by Michael M. Dougherty and John Gieringer. We'd like to thank the authors of this textbook,
as this book has been important in creating the calculus foundation of first semester calculus on CalcU. Thank you
for making this stellar work available to the greater calculus community; we are all better off for it.

### Lecture Notes

These are two GNU free documentation calculus textbooks written by Sigurd Angenent, with notes and problems compiled by Joel Robbin. These notes have been important in helping us expand the calculus section of our website, and build upon a foundation with different ways of explaining the content, and a vast array of practice problems. We are all looking forward to their next project, a third semester calculus text!

### Example Problems Wiki

**Example Problem Wiki**
is a site that has compiled a large list of example problems which made up the very first questions in our database.
We'd like to thank to this community for building such a helpful and well described collection. If you run
into a beautiful practice problem in LaTex on the site, it can probably be attributed to this community.
