GeoGebra
Identity Crisis? Identity Resolution?
Hello mathematicians, puzzlers, and other curious people! Whilst doing homework for my numerical methods class (which is about getting computers to do math for you), and using GeoGebra to troubleshoot a result that wasn’t working out, I ran into an issue: GeoGebra’s expression for a derivative was different from what I had calculated by hand.…
Sun and Umbrellas: Beach Picture Craft Camp Video 3
Hello mathematicians, puzzlers, and other curious people! In this video, you can see how to add the sun and some umbrellas to your picture. Does anyone see how you could use the umbrellas to prove the same formula we proved with the seashells last time? Let me know if you figure it out! Calc You…
Seashells: Beach Picture Craft Camp Video 2
Hello mathematicians, puzzlers, and other curious people! This video shows the next step in assembling our beach pictures, putting some seashells in the sand. The next step will be up tomorrow, provided things go smoothly (or at least manageably). I\’ll also post a proof of that important fact about the inner angle sum of a…
Sand, Sea, and Sky: Beach Picture Craft Camp Video 1
Hello mathematicians, puzzlers, and other curious people! This video shows how to set up a background representing sand, sea, and sky so you can get started. Keep your eyes open, because the next step will be up soon. Calc You Later!
GeoGebra: Dynamic Color
Hello mathematicians, puzzlers, and other curious people! In this video I show how to experiment with dynamic color in GeoGebra. I\’d really like to see some things folks come up with this way! Carefully take a screenshot and feel free to post it in the comments. Calc You Later!
Snowflake
Hello mathematicians, puzzlers, and other curious people! As a test of a new streaming program I just livestreamed the process of making an animated Koch snowflake in GeoGebra. Right now because it took so long I\’m not planning to EVER do that again so here it is in the archives for you to enjoy if…
