patty's calculus videos

Patty Leitner, award-winning college math teacher, has been making instructional math videos for years, and has allowed me to link to her awesome patty's calculus videos.

 
Let Patty take you on a video journey through the land of calculus, clearly explaining the topics in her friendly style.

The 47 videos are grouped into four playlists:  Limits,   Derivatives,   Applications,  and  Integrals.
Each part has 10 to 14 videos of about 35 to 60 minutes. If you look carefully you can locate some free PDF handouts to fill in while you watch the videos. It's a proven educational bonanza, all for free to you and/or your students.

Students: If you like these videos, let Patty know! On twitter at @pattysmathclass or email her at pattysmathclass@gmail.com

Teachers: If you use these videos as a class resource, tell Patty and she can put your name on the "approved" list! On twitter at @pattysmathclass or email her at pattysmathclass@gmail.com

view dansmath models on cardboard!

Now I have figured out how to allow you, the viewer, to view my 3D viewable models in a Google Cardboard viewer!

Here's an example, but the general idea is that if you stick "/embed?cardboard=1" (without the quotes) after the model URL you will get a stereo viewable image for your Google Cardboard-compatible viewer.

 
Tap the image on your phone and put it in a Google Cardboard viewer.

I have one that I put together for under $8 (half of which was shipping). The Vel-cro was stronger than the Cardboard's cardboard, and it tore but still works, and the images look awesome.

I have now ordered a View-Master VR Viewer, usually $29.99, I got one for $21 (post-Xmas discount) and it should arrive in a couple of days. I'll let you know how that goes.

dansmath 3D logo embedded here!

After 18 years on the web, the last 16 of them at dansmath.com, I have finally achieved a major goal: to create 3D math art in mathematica, and upload it to my site where anyone can view, appreciate it, spin it around, and say, "Now that's math!"

During this month I have been uploading several of my models to sketchfab.com, and just today I began embedding them here. Hope you like it/them!

Please feel free to follow me on Twitter, leave comments here or at my sketchfab page, and tell others about your experience! Happy mathing!

dansmath.com - it's on!

Now at last I have renewed my Squarespace site, and I am repopulating and updating my legacy pages from www.dansmath.com as well as adding major new content.

 
 

In the coming weeks and months I hope to offer math lessons, a math art and movie gallery, embedded 3D models, and eventually a storefront for digital art prints, rolled or framed canvases, and various 3D-printed objects.

Happy Mathing!
