I’m excited to announce several changes to single variable Active Calculus along with some corresponding updates that will occur over the next month or so.
+ There is now a new HTML version of the text.
Thanks to Rob Beezer’s Mathbook XML (now called PreTeXt), this output format is optimized for viewing on a range of devices, including smartphones. Many times over the past several years I’ve had my students come into my office to ask a question, only to pull up the PDF of the text on their phone and pinch and squeeze their way to some problem or statement. The HTML version looks fantastic on a phone and is in many ways far superior to PDF; please check it out. I find it likewise better for viewing on a projector screen in a classroom.
+ The HTML version includes live WeBWorK exercises.
Thanks to the programming and technical support of Alex Jordan at Portland Community College, if you follow the link above and navigate to the end of any section, you’ll see each section starts with several WeBWorK exercises (usually 4-8 of them). These newly included exercises (all of which come from the OPL) are more routine than the original exercises in the text, which remain but are now numbered differently. The WeBWorK exercises provide live anonymous feedback; do note that even if your department is a WeBWorK platform, students can’t log in to complete these problems. These are intended to be optional supplementary exercises.
+ A corresponding new PDF version is forthcoming.
I’m still working to get the 2017 PDF ready; I expect that will take another couple of weeks, at which point I have to get it set up with Amazon. Regardless, that will be ready by the start of fall term (late August) for print versions. It will be important for users to download the 2017 PDF regardless, since the HTML version requires an internet connection to function. More to follow when the 2017 PDF posts. Also, see next item for why I’m writing “2017 PDF”.
+ The 2016 version will be available but unchanged going forward
The 2016 LaTeX/PDF version will continue to be available, but my plan is not to make any further changes to that source code and instead view that source as “frozen”. If in the past you have requested the original TeX source from me, you’re welcome to ask for the most updated version of that, which I last changed a month or so ago to reflect the errors that various users found and reported during the 16-17 academic year. This 2016 PDF version will continue to be posted online and will also be available for purchase in print/bound form from Amazon, etc.
Looking ahead to the start of fall semester: if you use either the 2016 or 2017 version and intend to encourage your students to buy a print copy, it will be important that you clearly direct students to the correct print version to purchase. There is a new cover image and a slightly different color scheme for 2017 to help distinguish the two versions. More info on this (with direct links) will follow — for sure on my blog and likely via email — sometime in mid August, including an overview of the differences between the two versions, which are modest but will likely affect communication with students when directing them to portions of the text.
+ Active Calculus – now on GitHub
For GitHub users and those interested in using/learning Mathbook XML/PreTeXt, the XML source files are now on GitHub. I am a novice GitHub user, but as I continue to learn, submission of issues and pull requests will be very much appreciated. In the not-distant future I plan to post the 2016 LaTeX source files to GitHub as well.
+ More updates to follow
I’ve recently updated my web page for the text, and I expect that additional updates will follow there along with here on the blog in the coming weeks. Beyond information regarding this new version and format for the text, I’m planning to post more frequently this fall to share user feedback on the HTML version and some other hoped-for future developments.
Thanks for reading and for your interest in Active Calculus.
