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

$Wallis Sieve Area! In this short, we show how to build the Wallis Sieve using an iterative procedure of cutting remaining square lengths into the next odd and removing the created central square in the corresponding square grid. Along the way, we discuss how to compute the area of the resulting limiting shape as an infinite product. This infinite product is related to the famous Wallis product and so the shaded area is amazingly Pi/4.

$Alternating Geometric Series (ratio 1/2) This is a short, animated (wordless) visual proof demonstrating the sum of the infinite geometric series with ratio -1/2. To buy me a coffee, head over to https://www.buymeacoffee.com/VisualProofs Thanks! This animation is based on a visual proof by Ángel Plaza from the May 2018 issue of The College Math Journal page 200 (https://doi.org/10.1080/07468342.2018.1437302). #mathshorts #mathvideo #math #calculus #mtbos #manim #animation #theorem #pww #proofwithoutwords #visualproof #proof #iteachmath #geometricseries #infiniteseries #fractals #sum #induction To learn more about animating with manim, check out: https://manim.community$
