$Lévy C: Copy; Rotate 90; shift new start to old end Lévy C: Copy; Rotate 90; shift new start to old end In this video, we show how to generate a fractal curve known as the Lévy C curve or Lévy Dragon by repeatedly copying, rotating and shifting, starting with a line segment. What happens if you do something similar with different rotations or different shifts?

$Visualizing Fraction Addition in Circles This is a short animation showing how to think visually about adding fractions. We show the process only for 4/7+1/3 but a similar idea works for adding any pair of fractions. To buy me a coffee, head over to https://www.buymeacoffee.com/VisualProofs Thanks! This is a standard technique for visualizing fraction addition. #mathshorts #mathvideo #math #fractions #mtbos #manim #animation #theorem #pww #proofwithoutwords #visualproof #proof #iteachmath #mathematics #area #visualfractions #addfractions #fractionarithmetic #arithmetic To learn more about animating with manim, check out: https://manim.community$
