Long live Sir Davis.😊😊 11 Pompé Pompé 2 years ago this should have a million views. best for visual learners of math like me 162 Chromie Doodles Chromie Doodles 1 year ago Excellent presentation. I never had Geometry and was homeschooled and now I'm in college trig. This tutorial is a lifesaver and better now than never although I wish I'd seen it 2 weeks ago before class started. Appreciate you creating this content and look forward to watching your other vids. 17 Anime lover Anime lover 7 months ago This deserves millions of views. My teachers told me to cram T-raios without explaining what they actually are, and that's where this becomes annoying. Thank you very much for providing such a great video learning by visualisation and understanding can make anything easier.
