Drawing vectors with arrow-heads. about article HOT 5 OPEN

PS - I got it mostly working the way I like! Just would like the vectors to look like vectors.

Sounds great! Emailing...

So cool that you got this working -- saw that you converted a few other things over as well! Are these used in university courses? Would love to know more!

Absolutely agree that vector heads are necessary, will leave this open!

Hey Rowan. Yes to university courses: over ~15 years I've written various interactive teaching tools but over time things like Flash & Java applets have stopped running in browsers.
This utility will be used in my Electronics & Circuit Theory course at Belmont University in Spring 2021.

Actually, that was so easy that yesterday I re-did a similar demo on Simple Harmonic Motion for my Acoustics course: https://hedges.belmont.edu/~shawley/physapplets/shm.html

I appreciate how iooxa/article allowed me to focus on the math instead of having to build all the graphics & interaction, all so that my students can focus on the graphics & interaction instead of the math! ;-)

Working on an interactive eBook next. Not sure how many JS libraries I'll need (e.g. using vis.js for 3D), but I appreciate how your "scoping" functionality allows one to keep things separate.

I found that one in browsing through your apps pages, I really love the hiding and showing intro text and equations. I have tried to do something similar here:

By having a slider that changes from a 2min interactive read/graphic to an in-depth proof.

Glad you found the scoping easy, and makes sense to you!

One of the other things I am in the process of getting off the ground is iooxa.com. It aims to support these sort of interactive textbook-like environments, and also take care of some of the collaboration aspects that come with re-using, writing and getting help from other folks. We found that github was a bit too challenging to most of the people who would actually write content, learning from developing a geophysics textbook.

I would love to chat/hear more about your eBook plans if you would be up for it!
